In order to further solve the technical problem, an embodiment of the present invention further provides an artificial nervous system, which includes the above-mentioned integrated computing unit.
Compared with the prior art, the technical scheme provided by the embodiment of the invention has the beneficial effects that:
1. the preparation method of the integrated unit capable of storing and calculating provided by the embodiment of the invention can be used for constructing a device structure which has an energy storage function, an information storage function and a calculation function at the same time, and is a brand-new operation architecture.
The battery can be formed by the first electrode, the electrolyte layer and the second electrode, and has the function of storing electric energy. When switching between these at least two states, the content of the migratable charged particles in the electrodes changes, i.e. deintercalation and intercalation of the migratable charged particles between the first electrode and the second electrode occur, which is accompanied by a process of charging or discharging. If the process of discharging is carried out, the process can be driven by the originally stored electric energy in the battery structure; if a charging process occurs, this can be accomplished by an external power source or another battery structure consisting of the first electrode, the electrolyte layer and the second electrode. By controlling the charging and discharging, it is possible to flexibly switch between these states.
Compared with the current von Neumann-based computational separation architecture, the structure limitation of the transistor is broken, and the development potential is huge. Because the energy storage function is achieved, and the movable charged particles only move between the first electrode and the second electrode, the energy loss is small, and the overall power consumption is greatly reduced.
2. Within the range of at least one content of migratable charged particles of at least one of the first electrode and the second electrode, the content of migratable charged particles of at least one of the first electrode and the second electrode is in a one-to-one correspondence with the potential difference between the first electrode and the second electrode, and/or the content of migratable charged particles of at least one of the first electrode and the second electrode is in a one-to-one correspondence with the resistance value thereof.
In this way, within the range of the content of the at least one migratable charged particle in at least one of the first electrode and the second electrode, the number of state points corresponding to different migratable charged particle contents is theoretically infinite, and the number of state points with the required number can be selected according to actual design requirements, so that each structural unit consisting of the first electrode, the electrolyte layer and the second electrode can be greatly increased to have more distinguishable states, and more complex calculation and storage work can be completed. The larger the number of distinguishable states we have selected, the fewer the number of structural units required to be made up of the first electrode, the electrolyte layer and the second electrode, in the case of achieving a calculated amount of the same scale or a stored amount of the same scale; under the condition that the number of structural units formed by the first electrode, the electrolyte layer and the second electrode is unchanged, the more the number of the selected distinguishable states is, the stronger the calculation capacity and the storage capacity are. This design further expands the performance potential of the structural unit consisting of the first electrode, the electrolyte layer and the second electrode.
3. The potential variation of the first electrode is at least an order of magnitude lower than the potential variation of the second electrode with the same variation of the content of the migrateable charged particles within at least one range of the content of the migrateable charged particles of at least one of the first and second electrodes. This enables the potential difference between the first and second electrodes to be detected and controlled more accurately, thereby enabling the respective states to be monitored more accurately.
4. Lithium ions are used as migratable charged particles, and in a certain lithium ion content variation range, the lithium ion content in the electrode and the potential difference are in one-to-one correspondence, so that a plurality of different states can be selected from the lithium ion content and used as the basis for calculation and storage, and the limitation that the traditional transistor has only two states is broken through.
The lithium ion content and the inter-electrode potential difference of the selected electrodes corresponding to the different states are different and are in a continuous relationship, namely, the lithium ion content and the inter-electrode potential difference of the electrodes are continuously changed, so that the lithium ion content of the electrodes is traceable before and after the change, the inter-electrode potential difference becomes different once the lithium ion content of the electrodes is changed, and in the range of the one-to-one corresponding relationship, another point that the potential difference is equal to the potential difference does not exist, namely, each state has independence. In this way, the integrated unit can be stored to have a memory function for the electric charge passing through the integrated unit, namely, the electric charge passing through the integrated unit and the movement direction of the electric charge passing through the integrated unit can be reflected according to the electric potential difference before and after the state change of the integrated unit, so that the information or the change process can be memorized. The method can be used for calculation, information storage and information change process recording, realizes integration of energy storage, calculation and information storage, has the memory characteristic of charges passing through the method, and has the potential of building a neural network.
5. The composite structure layer composed of the Pt layer and the Ti layer enables the charge distribution around the first electrode to be more uniform, and the composite structure layer of the Pt layer and the Ti layer serves as a conductive layer and is beneficial to enabling the migratable charged particles to be more uniformly disengaged from or re-engaged with the first electrode. The Ti layer can also improve the interface adhesion, so that the first electrode is more fully combined with the composite structure layer of the Pt layer and the Ti layer, and the charge transfer is smoother.
6.Au-SiO 2 The layer can greatly improve the reversibility of the insertion and the extraction of the lithium ions, and the reduction of the variable concentration range of the lithium ions in the second electrode is avoided, so that the wide variable concentration range of the lithium ions is ensured, and more distinguishable states are provided.
7. The edge of the electrolyte layer extending toward the surface of the substrate, or the edge of the electrolyte layer extending beyond at least one of the first electrode and the second electrode, can sufficiently separate the first electrode and the second electrode.
8. Form a first drainage electrode and a second drainage electrode, first drainage electrode and first electrode electric connection, second drainage electrode and second electrode electric connection, like this, just formed both ends device, can distinguish the state through the potential difference that detects between first electrode and the second electrode.
9. Form a first drainage electrode and two second drainage electrodes, first drainage electrode and first electrode electric connection, two second drainage electrodes divide the both ends of locating the second electrode and all with second electrode electric connection in order to be used for detecting the resistance of second electrode, like this, just formed the three-terminal device, can come to distinguish the state through the resistance that detects the second electrode.
10. By adopting a mask method and a physical vapor deposition/additive manufacturing mode, each functional layer can be conveniently prepared and is convenient to integrate.
11. The integrated storage and calculation unit breaks through the structural limitation of the traditional calculation unit, realizes the integration of energy storage, calculation and information storage, has smaller power consumption, higher energy utilization rate, lower calculation time delay and stronger calculation power, has the memory characteristic, and has potential value in application to an artificial neural network system.
12. The computing module of the processor has the functions of energy storage, computing and information storage, the whole framework and the structure are more simplified, the size is smaller, the power consumption is lower, the computing time delay is lower, the computing power is stronger, the dependence on external energy is greatly reduced, and the processor can be used for dealing with emergency situations. In addition, the technical limit of the traditional transistor is broken through, the development space is larger, and the artificial neural network system has the value of building an artificial neural network system.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
The embodiment of the invention provides a preparation method of a calculation-capable integrated unit, a processor, electronic equipment and a nerve-like system. The description will be specifically made.
Example 1
The embodiment provides a preparation method of a storage and calculation integrated unit, which comprises the following steps: a substrate 110 is provided, and a first electrode 120 or a second electrode 140 is formed on the surface of the substrate 110.
As shown in fig. 1, when the first electrode 120 is formed on the surface of the substrate 110, the electrolyte layer 130 is formed on the surface of the first electrode 120 away from the substrate 110, and the second electrode 140 is formed on the surface of the electrolyte layer 130 away from the first electrode 120.
As shown in fig. 2, when the second electrode 140 is formed on the surface of the substrate 110, the electrolyte layer 130 is formed on the surface of the second electrode 140 away from the substrate 110, and the first electrode 120 is formed on the surface of the electrolyte layer 130 away from the second electrode 140.
In the present embodiment, the first electrode 120 is formed on the surface of the substrate 110.
The first electrode 120 is used to provide migrateable charged particles, and the migrateable charged particles can be embedded into the second electrode 140 through the electrolyte layer 130 under the driving of electric energy, or can be de-embedded from the second electrode 140 after being embedded into the second electrode 140 under the driving of electric energy. In this way, the migrateable charged particles can be alternately inserted into and extracted from the first electrode 120 and the second electrode 140. In fact, the content of the migrateable charged particles in the first electrode 120 and the content of the migrateable charged particles in the second electrode 140 are changed synchronously, one of the contents is increased, and the other is necessarily decreased.
In the process of embedding or extracting the migratable charged particles into or from the second electrode 140, there are at least two states, under which the contents of the migratable charged particles in the first electrode 120 and the second electrode 140 are different, the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 and the potential difference between the first electrode 120 and the second electrode 140 are in a one-to-one correspondence relationship, and/or the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 and the resistance value thereof are in a one-to-one correspondence relationship. It is understood that the number of these states may be 2, 3, 4, 5, or even more, and may be flexibly selected according to the actual design requirements.
It should be noted that the "one-to-one correspondence" means that the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 in the at least two states is different, the potential difference between the first electrode 120 and the second electrode 140 corresponding to the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 in the two states is also different, and/or the resistance value of the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 in the two states is also different corresponding to the resistance value of the content of the migratable charged particles.
For example: after the content of the mobile charged particles in at least one of the first electrode 120 and the second electrode 140 changes (from one state to another of the at least two states), the potential difference between the first electrode 120 and the second electrode 140 changes, and/or the resistance value of at least one of the first electrode 120 and the second electrode 140 changes. In this way, the at least two states can be characterized by the potential difference between the first electrode 120 and the second electrode 140 and/or the resistance of at least one of the first electrode 120 and the second electrode 140 in the at least two states, i.e., the at least two states can be distinguished by the potential difference between the first electrode 120 and the second electrode 140 and/or the resistance of at least one of the first electrode 120 and the second electrode 140, and then the calculation, for example, "0, 1 calculation" can be performed by the transition between the at least two states, or the storage and characterization of information can be performed by the transition between the at least two states. By integrating a large number of basic structures consisting of the first electrode 120, the electrolyte layer 130, and the second electrode 140, complicated arithmetic operations and information storage operations can be performed.
It is understood that in the at least two states, the at least two states can be characterized as long as at least one of the potential difference between the electrodes and the resistance value of the electrodes has a different value.
The at least two states can be characterized by the potential difference between the first electrode 120 and the second electrode 140, the at least two states can also be characterized by the resistance of the electrodes, and of course, the at least two states can also be characterized by the potential between the first electrode 120 and the second electrode 140 and the resistance of the electrodes at the same time.
Through the above design, the first electrode 120, the electrolyte layer 130 and the second electrode 140 can constitute a battery, and have a function of storing electric energy. When switching between these at least two states, the content of the migratable charged particles of the second electrode 140 changes, i.e., deintercalation and intercalation of the migratable charged particles occur between the first electrode 120 and the second electrode 140, which may be accompanied by a process of charging or discharging. If the process of discharging is carried out, the process can be driven by the originally stored electric energy in the battery structure; if a charging process occurs, this may be accomplished by an external power source or another battery structure consisting of the first electrode 120, the electrolyte layer 130, and the second electrode 140. By controlling the charging and discharging, it is possible to switch between these states flexibly.
The preparation method of the integrated unit capable of storing and calculating can build a device structure with an energy storage function, an information storage function and a calculation function at the same time, and is a brand new operation framework. Compared with the current von Neumann-based computational separation architecture, the structure limitation of the transistor is broken, and the development potential is huge. Because the energy storage function is achieved, and the migratable charged particles only move between the first electrode 120 and the second electrode 140, the energy loss is small, and the overall power consumption is greatly reduced.
In order to make the structure formed by the first electrode 120, the electrolyte layer 130 and the second electrode 140 have more distinguishable states, when the materials of the first motor and the second electrode 140 are selected, the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 and the potential difference between the first electrode 120 and the second electrode 140 are in a one-to-one correspondence relationship, and/or the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140 and the resistance value thereof are in a one-to-one correspondence relationship, in the range of the content of the migratable charged particles in at least one of the first electrode 120 and the second electrode 140.
In this way, within the range of the content of the at least one migratable charged particle in at least one of the first electrode 120 and the second electrode 140, the number of state points corresponding to different contents of the migratable charged particle is theoretically infinite, and the number of state points with the required number can be selected according to the actual design requirement, so that each structural unit consisting of the first electrode 120, the electrolyte layer 130 and the second electrode 140 can be greatly increased to have more distinguishable states, and thus more complex calculation and storage work can be completed. The larger the number of distinguishable states we have chosen, the fewer the number of structural units required to be made up of the first electrode 120, the electrolyte layer 130 and the second electrode 140 in the case of achieving a calculated amount on the same scale or a stored amount on the same scale; in the case where the number of structural units formed by the first electrode 120, the electrolyte layer 130, and the second electrode 140 is not changed, the larger the number of distinguishable states is, the stronger the calculation capability and the storage capability thereof are. This design further expands the performance potential of the structural unit consisting of the first electrode 120, the electrolyte layer 130 and the second electrode 140.
In order to enable the potential difference between the first electrode 120 and the second electrode 140 to be detected and controlled more accurately, the potential variation of the first electrode 120 is at least an order of magnitude lower than the potential variation of the second electrode 140 in the case of the same content variation of the migratable charged particles within at least one content range of the migratable charged particles of at least one of the first electrode 120 and the second electrode 140 as described above. It should be noted that "one order of magnitude lower" means that the index of 10 is 1 less in magnitude when the value of the change in potential is expressed by scientific expression.
It will be appreciated that the potential change of the first electrode 120 may be one order of magnitude, two orders of magnitude, three orders of magnitude, or even more than the potential change of the second electrode 140 with the same content of migrateable charged particles, and is not limited thereto, and that in general, the smaller the potential change of the first electrode 120 compared to the potential change of the second electrode 140, the more advantageous is the accurate detection and control of the potential difference between the first electrode 120 and the second electrode 140, thereby enabling the respective states to be monitored more accurately.
Alternatively, the specific material of the first electrode 120 may be selected such that the potential of the first electrode 120 is kept relatively constant in the range of at least one content of the migratable charged particles of at least one of the first electrode 120 and the second electrode 140, i.e. the potential of the first electrode 120 is substantially constant with the content of the migratable charged particles. At this time, the change in the potential difference between the first electrode 120 and the second electrode 140 is mainly determined by the potential of the second electrode 140, which makes it easier to accurately monitor the potential difference between the first electrode 120 and the second electrode 140.
Specifically, the material of the substrate 110 is Si 100, the substrate 110 is cut into a square with a side length of 4 inches, and the substrate 110 is cleaned with absolute ethyl alcohol.
Referring to fig. 3, 4 and 5, before forming the first electrode 120 on the surface of the substrate 110, a Pt electrode array pattern is first formed on the surface of the substrate 110 by applying a photoresist, exposing, cleaning and developing, pt is plated on the Pt electrode array pattern on the surface of the substrate 110 by magnetron sputtering, and Ti is plated on the Pt electrode array pattern, so that the Ti layer 160 is located on a side of the Pt layer 150 away from the substrate 110. Wherein the sum of the thicknesses of the Pt layer 150 and the Ti layer 160 can be controlled within a range of 50nm-2 μm. The area of the Pt layer 150 is the same as that of the Ti layer 160, and both are square, and the side length can be controlled in the range of 4nm to 50 μm, but is not limited thereto.
The operation steps for preparing the Pt layer 150 and the Ti layer 160 by magnetron sputtering include, but are not limited to:
mounting a Pt target, and putting the Pt target into the substrate 110;
pumping the air pressure in the chamber to 5 x 10 -4 Pa or less;
introducing argon gas, adjusting the air pressure of the cavity to 2Pa, setting the power of Pt to 30W, and adjusting the air pressure to 1Pa after starting;
pre-sputtering for 10min to remove impurities on the surface of the target, and then performing thin film sputtering for 20min;
and (3) replacing the Ti target material for sputtering, setting the sputtering power of Ti to be 20W, and setting the sputtering time to be 20min.
By performing the above process before forming the first electrode 120, the charge distribution around the first electrode 120 can be more uniform by the composite structure layer of the Pt layer 150 and the Ti layer 160, and the composite structure layer of the Pt layer 150 and the Ti layer 160 serves as a conductive layer, which helps to more uniformly de-embed or re-embed the migratable charged particles from or into the first electrode 120. In addition, the Ti layer 160 can improve the interface adhesion, so that the first electrode 120 is combined with the composite structure layer of the Pt layer 150 and the Ti layer 160 more sufficiently, and the charge transfer is smoother.
Referring to fig. 6 and 7, after the composite structure layer of the pt layer 150 and the Ti layer 160 is formed, a pattern of the first electrode 120 is formed on a surface of the Ti layer 160 away from the substrate 110 by applying a photoresist, exposing, cleaning, and developing, in this embodiment, the first electrode 120 is formed byLiCoO 2 I.e. using LiCoO 2 Lithium ions are provided as migratable charged particles, and the state is switched by the insertion and extraction of lithium ions between the electrodes.
LiCoO is coated on the pattern of the first electrode 120 by means of magnetron sputtering 2 To form the first electrode 120, the thickness of the first electrode 120 may be controlled to be 1nm-100 μm, the first electrode 120 has a square shape, the side length may be controlled to be 2nm-45 μm, one side edge of the first electrode 120 is flush with one side edge (side a shown in fig. 6) of the composite structure layer of the Pt layer 150 and the Ti layer 160, and the first electrode 120 is disposed at an intermediate position of the side edge of the composite structure layer a of the Pt layer 150 and the Ti layer 160, but is not limited thereto.
The operation steps for preparing the first electrode 120 by magnetron sputtering include, but are not limited to:
installing LiCoO 2 A target material;
pumping the air pressure in the chamber to 5 x 10 -4 Pa below;
introducing argon and oxygen, adjusting the pressure of the cavity to 2Pa, adjusting the flow rate of the argon to 200sccm and the flow rate of the oxygen to 5sccm, and setting LiCoO 2 The power of the gas source is 100W, and the gas pressure is adjusted to 1Pa after the gas source is started;
pre-sputtering for 10min to remove impurities on the surface of the target, and then performing thin film sputtering for 40min.
The area of the first electrode 120 is smaller than the composite structure layer of the Pt layer 150 and the Ti layer 160, and a certain space is reserved on the composite structure layer of the Pt layer 150 and the Ti layer 160, so that the formation of the drainage electrode is facilitated.
Referring to fig. 8 and 9, after the first electrode 120 is formed, a pattern of the electrolyte layer 130 is formed on a surface of the first electrode 120 away from the substrate 110 by applying a photoresist, exposing, cleaning, and developing, in this embodiment, the electrolyte layer 130 is a solid electrolyte layer, and LiPON is plated on the pattern of the electrolyte layer 130 by magnetron sputtering to form the electrolyte layer 130, wherein the thickness of the electrolyte layer 130 can be controlled to be 1nm-10 μm.
Note that the edge of the electrolyte layer 130 near the a side extends toward the surface of the substrate 110, and the other edge extends beyond the edge of the first electrode 120 to sufficiently separate the first electrode 120 from the second electrode 140.
It is understood that in other embodiments of the present invention, all edges of the electrolyte layer 130 may extend all around directly along the surface of the electrolyte layer 130 beyond the edge of the first electrode 120 to substantially shield the first electrode 120, as shown in fig. 10; or both may extend toward the surface of the substrate 110 to wrap the first electrode 120, as shown in fig. 11. Both of these ways can substantially isolate the first electrode 120 from the second electrode 140. It should be noted that if the edge of the electrolyte layer 130 extends toward the surface of the substrate 110, the edge thereof near the a side may extend to the surface of the substrate 110, or may be spaced from the surface of the substrate 110; while the remaining edges may extend to the surface of the Ti layer 160 or may be spaced apart from the surface of the Ti layer 160.
The operation steps for preparing the electrolyte layer 130 by magnetron sputtering include, but are not limited to:
installing a LiPON target material;
pumping the air pressure in the chamber to 5 x 10 -4 Pa or less;
introducing nitrogen with the flow rate of 50sccm, adjusting the air pressure of the cavity to 2Pa, setting the power of the LiPON to 100W, and adjusting the air pressure to 1Pa after starting;
pre-sputtering for 10min to remove impurities on the surface of the target, and then performing thin film sputtering for 60min.
Referring to fig. 12 and 13, after the formation of the electrolyte layer 130 is completed, a second electrode is formed. In this embodiment, the second electrode is made of Au-SiO 2 And a bilayer structure of Cu. Au-SiO is developed on the surface of the electrolyte layer 130 far away from the first electrode 120 by means of photoresist coating, exposure, cleaning and development 2 In Au-SiO by means of magnetron sputtering 2 The pattern of (A) is plated with Au-SiO first 2 To form the first layer of the second electrode, the thickness of the Au — SiO2 layer 141 may be controlled to be 0.5nm to 100 μm. Au-SiO 2 The layer 141 is square and has the same area as the first electrode 120, au-SiO 2 One side edge of layer 141 is flush with the a-side edge, and Au-SiO 2 The layer 141 is provided at an intermediate position of the a-side edge, but is not limited thereto.
Due to Au-SiO 2 The layer 141 has the same shape and area as the first electrode 120, and the electrolyte layer 130 can sufficiently separate the first electrode 120 from the second electrode.
Wherein, the Au-SiO is prepared by magnetron sputtering 2 The operational steps of layer 141 include, but are not limited to:
mounting Au target and SiO 2 A target material;
pumping the air pressure in the chamber to 5 x 10 -4 Pa below;
introducing argon gas, adjusting the flow of the argon gas to 200sccm, adjusting the air pressure of the cavity to 2Pa, setting the power of Au to 30W, and setting SiO 2 The power of the air pressure adjusting device is 150w, and the air pressure is adjusted to 1Pa after the air pressure adjusting device is started;
pre-sputtering for 10min to remove impurities on the surface of the target, and then performing thin film sputtering for 30min.
In addition, au-SiO 2 The layer 141 can greatly improve the reversibility of insertion and extraction of lithium ions, and prevent the variable concentration range of lithium ions in the second electrode from being narrowed, thereby ensuring that there is a sufficiently wide variable concentration range of lithium ions, which helps to provide more distinguishable states.
Referring to FIGS. 14 and 15, au-SiO 2 After the layer 141 is formed, a second layer of the second electrode 140 is formed. Coating photoresist, exposing, cleaning and developing on Au-SiO 2 The surface of the layer 141 on the side far away from the electrolyte layer 130 shows a pattern of a Cu layer 142, cu is plated on the pattern of the Cu layer 142 by means of magnetron sputtering to form a second layer of the second electrode 140, and the thickness of the Cu layer 142 can be controlled to be 0.5nm-100 μm.
The edge of the Cu layer 142 near the a side extends toward the surface of the substrate 110 and extends to the surface of the substrate 110, and the Cu layer 142 continues to extend in the direction away from the a side on the surface of the substrate 110 to form an extension region 142a for forming a drain electrode. The other edge of the Cu layer 142 extends beyond the Au-SiO 2 The edges of layer 141.
Intercalation of lithium ionsAnd deintercalation mainly occurs in Au-SiO 2 The layers 141, 142 are primarily for conducting electricity to enable charge on Au-SiO 2 The layer 141 is distributed more uniformly, so that the lithium ions are more uniformly inserted and extracted, and the Cu layer 142 effectively improves Au-SiO 2 The conductive capability of layer 141.
In other embodiments of the present invention, the Cu layer 142 may not extend to the surface of the substrate 110, and only Au — SiO may be used 2 The layer 141 may be covered, and the drain electrode may be formed directly on the Cu layer 142 away from the Au-SiO 2 One side of layer 141. And is not limited thereto.
The operation steps for preparing the Cu layer 142 by magnetron sputtering include, but are not limited to:
mounting a Cu target;
pumping the air pressure in the chamber to 5 x 10 -4 Pa below;
introducing argon gas with the flow of 200sccm, adjusting the pressure of the cavity to 2Pa, setting the power of Cu to 30W, and adjusting the pressure to 1Pa after starting;
pre-sputtering for 10min to remove impurities on the surface of the target, and then performing thin film sputtering for 30min.
Through the design, in a certain lithium ion content variation range, the lithium ion content in the electrode and the potential difference between the electrodes are in one-to-one correspondence, so that a plurality of different states can be selected from the lithium ion content in the electrode and used as the basis for calculation and storage, and the limitation that the traditional transistor only has two states is broken through.
The lithium ion content and the inter-electrode potential difference of the selected electrodes corresponding to the different states are different and are in a continuous monotone change relationship, namely the lithium ion content in the electrodes and the inter-electrode potential difference are continuously monotone changed, so that the lithium ion content in the electrodes is traceable before and after the change, the inter-electrode potential difference becomes different once the lithium ion content in the electrodes is changed, and no point exists in the one-to-one corresponding relationship range where another potential difference is equal to the potential difference, namely, each state has independence. In this way, the integrated unit can be stored to have a "memory" function for the electric charges passing through it, or the integrated unit can be stored to have a "memory" function for the charging and discharging processes of it, that is, according to the potential difference before and after the state change, the electric charge passing through it and the moving direction of the electric charges passing through it can be reflected, or the charging/discharging amount of it can be reflected, so as to realize the "memory" of the information or the changing process. The characteristic can be used for calculation, information storage and information change process recording, realizes integration of energy storage, calculation and information storage, has the memory characteristic of charges passing through the characteristic, and has the potential of building a neural network.

Further, it is to be noted that the above-described preparation process is merely exemplary, and the substrate 110, the Pt layer 150, the Ti layer 160, the first electrode 120, the electrolyte layer 130, the Au — SiO layer are 2 The shapes, side lengths, thicknesses, and the like of the layer 141 and the Cu layer 142 may be different, and may be flexibly adjusted according to actual design requirements. The area, the side length and the thickness of each functional layer can be smaller or larger according to actual design requirements, and the functional layers can be increased or decreased according to the actual design requirements.
The thickness ratio of the first electrode 120, the electrolyte layer 130, and the second electrode 140 may be controlled to be 1: (0.1-100): (0.01-100). It is understood that the thickness ratio of the first electrode 120, the electrolyte layer 130, and the second electrode 140 may be 1:0.1:0.01, 1:1:0.1, 1:10: 1. 1:100: 100. 1:100: 10. 1:10:100, etc., and is not limited thereto.
The Pt layer 150, the Ti layer 160, the first electrode 120, the electrolyte layer 130, and Au-SiO were formed 2 Other types of physical vapor deposition methods, such as vacuum evaporation, ion plating, etc., may also be used for layer 141 and Cu layer 142. In addition, other masking methods may be used to form the pattern, and additive manufacturing may be used to form the functional layers. And is not limited thereto.
Referring to fig. 16, the method for preparing the integrated storable unit further includes: a first drain electrode 170 and a second drain electrode 180 are formed. The first drain electrode 170 is formed on a surface of the Ti layer 160 away from the substrate 110, and is electrically connected to the first electrode 120 through a composite structure layer of the Pt layer 150 and the Ti layer 160. The second drain electrode 180 is formed on a surface of the extension region 142a of the Cu layer 142 away from the substrate 110, and electrically connected to the second electrode 140. In this way, a two-terminal device is formed, and states can be distinguished by detecting a potential difference between the first electrode 120 and the second electrode 140. The first drain electrode 170 and the second drain electrode 180 are both made of Pt materials, the first drain electrode 170 and the second drain electrode 180 may also be formed by forming an electrode pattern by using a mask method, and then the first drain electrode 170 and the second drain electrode 180 are formed by physical vapor deposition.
Referring to FIG. 17, au-SiO may not be provided 2 Layer 141, and Cu layer 142 is used directly as the second electrode. In this way, a two-terminal device is also formed, and states can be distinguished by detecting a potential difference between the first electrode 120 and the second electrode 140. It is understood that the Cu layer 142 may not extend to the substrate 110, as shown in fig. 18.
Referring to fig. 19, it should be noted that, in other embodiments of the present invention, a first drain electrode 170 and two second drain electrodes 180 may also be formed. The first drain electrode 170 is formed on a surface of the Ti layer 160 away from the substrate 110, and is electrically connected to the first electrode 120 through a composite structure layer of the Pt layer 150 and the Ti layer 160. Two second current-guiding electrodes 180 are respectively arranged on Au-SiO 2 Both ends of layer 141 are combined with Au-SiO 2 Layer 141 is electrically connected for detection of Au-SiO 2 The resistance value of layer 141. At this time, the Cu layer 142 may not be provided. Thus, a three-terminal device is formed, which can be detected by Au-SiO 2 The resistance of the layer 141 distinguishes between the states.
Of course, au-SiO may not be provided 2 The layer 141 is directly used as the second electrode by using the Cu layer 142, as shown in fig. 20, at this time, two second drain electrodes 180 are respectively disposed at two ends of the Cu layer 142 and are electrically connected to the Cu layer 142. In this way, a three-terminal device is also formed,the states can be distinguished by detecting the resistance value of the Cu layer 142. It is understood that the Cu layer 142 may not extend to the substrate 110, as shown in fig. 21.
Referring to fig. 22, if the second electrode 140 is formed on the substrate 110, the Cu layer 142 and the Au — SiO layer may be formed on the surface of the substrate 110 in sequence 2 Layer 141, electrolyte layer 130, first electrode 120, ti layer 160, and Pt layer 150. It can be seen that the order of the layers is reversed. The Pt layer 150 may or may not extend to the surface of the substrate 110.
Example 2
Referring to fig. 23, the embodiment provides a cost-effective integrated unit 100, which is prepared by the method for preparing the cost-effective integrated unit 100 provided in embodiment 1.
The integrated battery storage and calculation unit 100 has a battery structure using lithium ions as a medium, and has a function of storing electric energy. When lithium ions are intercalated and deintercalated between the first electrode 120 and the second electrode 140, the lithium ion content in the electrodes may be changed, which may result in a change in the potential difference between the first electrode 120 and the second electrode 140. Different lithium ion contents in the electrodes indicate that the battery structure is in different states, and the different states correspond to different potential differences, so that the different states can be characterized by means of the potential differences, and the different states can be distinguished.
When switching between these at least two states, the content of the migrateable charged particles in the second electrode 140 changes, i.e., the deintercalation and intercalation of the migrateable charged particles between the first electrode 120 and the second electrode 140 occur, which is accompanied by the occurrence of the charging or discharging process. If the process of discharging is carried out, the process can be driven by the electric energy originally stored in the battery structure; if a charging process occurs, this may be accomplished by an external power source or another battery structure consisting of the first electrode 120, the electrolyte layer 130, and the second electrode 140. By controlling the charging and discharging, it is possible to flexibly switch between these states. The calculation can be done by means of transitions between states, and the storage and characterization of information can also be achieved by means of transitions between states. By integrating a large number of the calculation-capable integrated units 100, complicated calculation work and information storage work can be completed.
In the conventional von neumann-based infrastructure, the memory and the processing unit are separated from each other and belong to different units, and the reading speed of information and the total amount of information readable per unit time by the processing unit also impose a limit on the performance of the processing unit. In order to improve the performance of the processing unit, a way of setting a multi-level cache is adopted at present, which not only increases the overall power consumption, but also increases the overall volume.
On the other hand, in order to further improve the performance of the existing processing unit, the integration level of the unit area is continuously increased, and the operating frequency of the processor is improved, so that not only is the power consumption obviously improved, but also the situations of heat accumulation and local burst of heat are easily caused, the requirement on heat dissipation is very high, and the risk of overheating and melting down of the processing unit is increased. This not only increases the energy consumption, but also makes the technical difficulty of heat dissipation very high.
In addition, the existing processing unit is in the form of an integrated transistor, the circuit path of the existing processing unit is very long, the heat generation is very serious, and the power loss ratio is very high. Furthermore, once the work is started, the processing unit and the storage unit need to be continuously powered, and the dependence on external energy sources is very high.
The computing-capable integrated unit 100 breaks the limitations of the traditional infrastructure and employs an electrochemical-like cell structure. In the working process, when the state is switched, lithium ions only move between the first electrode 120 and the second electrode 140, the movement path is very short, the energy dissipation is very little, the overall energy loss is reduced, the energy efficiency ratio is improved, the calculation time delay is low, and the calculation force is strong.
The energy storage and calculation integrated unit 100 itself has an effect of storing electric energy, and during operation, state switching can be realized by consuming the electric energy stored by itself. Particularly, when a large number of the energy storage/integration units 100 are integrated, the state switching of each energy storage/integration unit 100 may use not only the electric energy stored in itself but also the electric energy stored in the surrounding energy storage/integration units 100. In this way, it may be that the totality capable unit 100 is able to operate without external energy supply for a certain time, reducing the dependence on external energy.
In addition, the lithium ion content in the electrode of the calculation integration unit 100 and the potential difference are in one-to-one correspondence in a certain lithium ion content variation range, so that a plurality of different states can be selected from the lithium ion content and the potential difference as the basis for calculation and storage, and the limitation that the traditional transistor only has two states is broken through.
The lithium ion content and the inter-electrode potential difference of the selected electrodes corresponding to the different states are different and are in a continuous relationship, namely, the lithium ion content and the inter-electrode potential difference of the electrodes are continuously and monotonically changed, so that the lithium ion content of the electrodes is traceable before and after the change, the inter-electrode potential difference becomes different once the lithium ion content of the electrodes is changed, and no point exists where another potential difference is equal to the potential difference within the one-to-one relationship range, namely, each state has independence. In this way, the integrated unit 100 can be stored to have a "memory" function for the electric charges passing through it, that is, according to the electric potential difference before and after the state change, the electric charge passing through it and the moving direction of the electric charges passing through can be reflected, and information or change process can be "memorized". The method can be used for calculation, information storage and information change process recording, realizes integration of energy storage, calculation and information storage, has the memory characteristic of charges passing through the method, and has the potential of building a neural network.
During the use of the integrated energy storage and calculation unit 100, the internally stored electric energy is gradually reduced and can be supplemented by using external energy. If the energy-computing integrated unit 100 is directly charged with energy by using external energy, the information originally stored in the energy-computing integrated unit 100 is erased once.
If the information originally stored in the integrated calculation and energy storage unit 100 needs to be stored, when the state of the integrated calculation and energy storage unit 100 changes, the energy released by the integrated calculation and energy storage unit can be used for charging another integrated calculation and energy storage device, and the state of the integrated calculation and energy storage device can be recorded, so that the original stored information is prevented from being lost. The integrated storage and calculation unit 100 may also be used to supplement the electric quantity required in the working process each time the unit works, so that the unit can smoothly complete the calculation, and thus, the continuity of information can be maintained, and the information loss can be prevented.
In general, the energy storage and computation integrated unit 100 breaks through the architectural limitation of the traditional computation unit, realizes the integration of energy storage, computation and information storage, has smaller power consumption and higher energy utilization rate, has a memory characteristic, and has a potential value of being applied to an artificial neural network system.
Note that the calculation-capable integrated unit 100 may be prepared by a modified embodiment of example 1, and is not limited thereto.

When switching between these at least two states, the content of the migratable charged particles of the second electrode changes, i.e. deintercalation and intercalation of the migratable charged particles between the first electrode and the second electrode occur, which is accompanied by a process of charging or discharging. If the process of discharging is carried out, the process can be driven by the electric energy originally stored in the battery structure; if a charging process occurs, this can be accomplished by an external power source or another battery structure consisting of the first electrode, the electrolyte layer and the second electrode. By controlling the charging and discharging, it is possible to switch between these states flexibly.
Compared with the current von Neumann-based computational separation architecture, the structure limitation of the transistor is broken, and the development potential is huge. Because the energy storage function is achieved, and the movable charged particles only move between the first electrode and the second electrode, the energy loss is small, and the overall power consumption is greatly reduced.
2. Within the range of at least one content of the migratable charged particles in the second electrode, the content of the migratable charged particles in the second electrode is in one-to-one correspondence with the potential difference between the first electrode and the second electrode, and/or the content of the migratable charged particles in the second electrode is in one-to-one correspondence with the resistance value of the second electrode.
In this way, within the range of the content of the at least one migratable charged particle of the second electrode, the number of the state points corresponding to different migratable charged particle contents is theoretically infinite, and the number of the state points with the required number can be selected according to the actual design requirement, so that each structural unit consisting of the first electrode, the electrolyte layer and the second electrode can be greatly increased to have more distinguishable states, and more complex calculation and storage work can be completed. The larger the number of distinguishable states we have chosen, the fewer the number of structural units that need to be made up of the first electrode, the electrolyte layer and the second electrode, in the case of achieving a calculated volume of the same scale or a stored volume of the same scale; under the condition that the number of structural units formed by the first electrode, the electrolyte layer and the second electrode is unchanged, the more distinguishable states are selected, the stronger the calculation capacity and the storage capacity are. This design further expands the performance potential of the structural unit consisting of the first electrode, the electrolyte layer and the second electrode.
3. The potential variation of the first electrode is at least an order of magnitude lower than the potential variation of the second electrode within the range of at least one content of migrateable charged particles of the second electrode for the same content of migrateable charged particles. This enables the potential difference between the first and second electrodes to be detected and controlled more accurately, thereby enabling the respective states to be monitored more accurately.
4. Lithium ions are used as migratable charged particles, and in a certain lithium ion content variation range, the lithium ion content in the electrode and the potential difference are in one-to-one correspondence, so that a plurality of different states can be selected from the lithium ion content and used as the basis for calculation and storage, and the limitation that the traditional transistor has only two states is broken through.
The lithium ion content and the inter-electrode potential difference in the selected electrodes corresponding to the different states are different and are in a continuous relationship, that is, the lithium ion content in the electrodes and the inter-electrode potential difference are continuously changed, so that the lithium ion content in the electrodes is traceable before and after the change, the inter-electrode potential difference becomes different once the lithium ion content in the electrodes is changed, and in the range of the one-to-one relationship, another potential difference equal to the potential difference does not exist, that is, each state has independence. In this way, the integrated unit can be stored to have a memory function for the electric charge passing through the integrated unit, namely, the electric charge passing through the integrated unit and the movement direction of the electric charge passing through the integrated unit can be reflected according to the electric potential difference before and after the state change of the integrated unit, so that the information or the change process can be memorized. The method can be used for calculation, information storage and information change process recording, realizes integration of energy storage, calculation and information storage, has the memory characteristic of charges passing through the method, and has the potential of building a neural network.
5. The composite structure layer composed of the Pt layer and the Ti layer enables the charge distribution around the first electrode to be more uniform, and the composite structure layer of the Pt layer and the Ti layer serves as a conductive layer and is beneficial to enabling the migratable charged particles to be more uniformly disengaged from or re-engaged with the first electrode. The Ti layer can also improve the interface adhesion, so that the first electrode is more fully combined with the composite structure layer of the Pt layer and the Ti layer, and the charge transfer is smoother.
6.Au-SiO 2 The layer can greatly improve the reversibility of the insertion and the de-insertion of lithium ions, and avoid the reduction of the variable concentration range of the lithium ions in the second electrode, thereby ensuring that the electrode has enough energyA wide enough variable concentration range of lithium ions to help provide more distinguishable states.
7. The edge of the electrolyte layer extending toward the surface of the substrate, or the edge of the electrolyte layer extending beyond at least one of the first electrode and the second electrode, can substantially isolate the first electrode from the second electrode.
8. Form a first drainage electrode and a second drainage electrode, first drainage electrode and first electrode electric connection, second drainage electrode and second electrode electric connection, like this, just formed both ends device, can distinguish the state through the potential difference that detects between first electrode and the second electrode.
9. Form a first drainage electrode and two second drainage electrodes, first drainage electrode and first electrode electric connection, two second drainage electrodes divide the both ends of locating the second electrode and all with second electrode electric connection in order to be used for detecting the resistance of second electrode, like this, just formed the three-terminal device, can come to distinguish the state through the resistance that detects the second electrode.
10. By adopting a mask method and a physical vapor deposition/additive manufacturing mode, each functional layer can be conveniently prepared and is convenient to integrate.
11. The integrated unit for storing and calculating breaks through the structural limitation of the traditional calculating unit, realizes the integration of energy storage, calculation and information storage, has smaller power consumption, lower calculation time delay, stronger calculation power and higher energy utilization rate, has the memory characteristic, and has potential value applied to an artificial neural network system.
