Definitions
- This invention relates to a method of making a nickel-coated copper substrate for use in a thin film composite and thin film composites containing such nickel-coated copper substrates.
- Energy storage devices made of thin film composites have been found to be useful in electronic and optoelectronic applications, such as ferroelectric memory devices, pyroelectronic sensor devices, waveguide modulators, and acoustic sensors.
- thin film composites are used in a variety of semiconductor integrated circuit devices such as analog circuits, rf circuits, and dynamic random access memories (DRAM's).
- the composites are usually composed of a substrate, a dielectric, and an electrode; the dielectric being between the substrate and the electrode.
- Substrates are commonly composed of copper, silicon, fused silica, platinum-coated silicon, alumina, sapphire, platinum-coated sapphire, or a single crystal SrTiO substrate.
- Copper is often preferred as a substrate in light of its ready availability.
- thin film composites having copper substrates often evidence thermal migration and outgassing.
- Thermal migration is the migration of copper ions into the dielectric and of ions in the dielectric into the substrate at elevated temperatures.
- Outgassing occurs when gaseous copper atoms escape from the substrate into either the dielectric or the oven in which deposition of the dielectric occurs.
- a copper substrate which eliminates these drawbacks is desired.
- the invention relates to a method of preparing a copper substrate having nickel deposited thereon.
- the invention relates to thin film composites containing such nickel-coated copper substrates.
- the nickel-coated substrate is prepared by depositing nickel onto the copper and then annealing the resulting substrate.
- the copper may be a foil. After annealing, a dielectric may be deposited onto the substrate by methods known in the art such as by sol-gel or vacuum deposition techniques.
- FIG. 1 is a graph depicting optimum temperatures and durations for annealing the nickel-coated substrate in accordance with the process of the invention
- FIG. 2 is an internal structure of a nickel-coated copper substrate pre-annealed at
- FIG. 3 is an internal structure of a nickel-coated copper substrate pre-annealed at
- FIGS. 4 and 5 are internal structures of a nickel-coated copper substrate pre- annealed at a temperature of 800° C for 20 minutes using a scanning electron microscope.
- FIG. 6 is an internal structure of a nickel-coated copper substrate pre-annealed at a temperature of 500° C for 90 minutes using a scanning electron microscope.
- FIG. 7 is an internal structure of a nickel-coated copper substrate pre-annealed at a temperature of 650° C for 30 minutes using a scanning electron microscope.
- FIG. 8 depicts a thin film composite in accordance with the invention having a copper substrate coated on its top and bottom surfaces with nickel, a dielectric, an optional barrier or buffer layer, and a top electrode.
- FIG. 9 depicts a thin film composite in accordance with the invention having a copper substrate completely enveloped by nickel.
- the thin film composites in accordance with the invention contain a nickel-coated copper substrate and a dielectric.
- the substrate is prepared by depositing nickel onto copper.
- the nickel may be deposited on one or both sides of the copper substrate.
- the nickel encapsulates the copper substrate.
- the nickel-deposited copper substrate is then annealed at a temperature between approximately 400°C and 820°C, preferably approximately 800°C.
- the optimum temperature between approximately 400°C and 820°C, preferably approximately 800°C.
- duration of annealing varies with the annealing temperature. For example, annealing at 400°C desirably lasts for about 120 minutes, while annealing at 800°C desirably lasts for about 20 minutes.
- FIG. 1 illustrates the optimum annealing temperatures and time durations wherein the most preferred temperature and time durations are those points on the line. Less acceptable results causing flawed substrates occur with increasing distance from the line. Flawed substrates include those exhibiting an unacceptable dielectric constant, high voltage leakage, or delamination.
- the thickness of the substrate is between about 20 to about 50 microns.
- the thickness of the Ni on the side contiguous to the dielectric is between from about 0.10 microns to about 2.0 microns.
- the thickness of the Ni on the bottommost surface of the substrate is between 0.1 to about 10 microns.
- the nickel may be applied to the copper substrate by sputtering or by other means known in the art.
- the pre-annealing and nickel deposition steps preferably occur in an atmosphere free of oxygen, such as in a gaseous atmosphere of argon or nitrogen.
- Pre- annealing refers to annealing prior to the deposition of dielectric material.
- Deposition of the dielectric on the nickel-coated copper substrate generally requires a low processing temperature to minimize interdiffusion and reaction between the foil and the dielectric.
- Such dielectrics may further be applied to the substrate by sol- gel (where the deposition occurs at room temperature and thus the annealed nickel-coated copper substrate is cooled to room temperature) or vacuum deposition (including sputtering, electron beam evaporation, and other techniques) where the annealed product is cooled to the temperature at which the deposition occurs.
- sol- gel where the deposition occurs at room temperature and thus the annealed nickel-coated copper substrate is cooled to room temperature
- vacuum deposition including sputtering, electron beam evaporation, and other techniques
- the dielectric is applied at elevated temperature of between 300 about 400° C. Deposition of the dielectric may occur in a single step or in multiple steps.
- the thickness of the dielectric varies depending on the amount of voltage desired of the resulting end product, such as capacitor. The higher the voltage is to be applied, the thicker the dielectric will likely be. A fairly typical thickness for the dielectric is about 600 nm.
- the dielectric is a lead zirconate titanate, PZT, of the formula Pb a L b Zr x Ti y O 7 wherein L is a lanthanide metal, preferably La or Nb, x and y are independently between from about 0.35 to about 0.65, z is from about 2.5 to about 5.0, a is from about 0.95 to about 1.25 and b is from about 0.02 to about 0.10.
- Such dielectrics may be prepared by using, as starting materials, lead acetate [Pb(CIl 3 COO) 2 H 2 O)], zirconium n-propoxide [Zr(O-nC 3 H 7 ) ], titanium isopropoxide [Ti(O-iC 3 Fl 7 ) ] and lanthanum isopropoxide [La(O-iC 3 H 7 ) 3 ] or niobium ethoxide [Nb(OC 2 II 5 ) 5 ].

- Ti(O-iC 3 Fl 7 ) titanium isopropoxide
- La(O-iC 3 H 7 ) 3 lanthanum isopropoxide
- Nb(OC 2 II 5 ) 5 niobium ethoxide
- Zirconium n-propoxide and titanium isopropoxide in 2-methoxyethanol may then be admixed with the resulting product which is at room temperature, then refluxed at 110°C for about 2 to 3 hours under vacuum from which polymer precursors, such as those of the formula Pb(Zr 0 . 5 Ti 0 . 48 )O 3 , may be obtained.
- the 0.3 M stock solutions may be obtained by dilution with toluene and adding appropriate formamade for protecting from crack and 10 mol% excess Pb for loss of lead oxide during the final annealing processing.
- barium titanate dielectrics especially those of the formula Ba a Ti t ,O c wherein a and b are independently between 0.75 and 1.25 and c is 2.5 to about 5.0 as well as those of the formula M a B b Ti c O d wherein a is about 0.01 to about 0.1, b is about 0.75 to about 1.25, c is about 0.75 to about 1.25 and d is about 2.5 to about 5.0 and M is a non-reactive elctroconductive metal.
- M are gold, copper, intermetallic compounds such as Ni 3 Al, Ru and InSn.
- Such barium dielectrics are discussed in PCT WO/98/07167, published on February 19, 1998, herein incorporated by reference.
- the product is annealed at between 500° and 600° C for
- the annealing temperature at this stage may be shorter if higher temperatures are used. Annealing is terminated when the desired result is achieved.
- the pre-annealing step should occur at a higher temperature than the annealing temperature for deposition of the dielectric onto the substrate; the latter being referred to as a "post- annealing" step. If the pre-annealing step is at a temperature lower temperature than the post-annealing step, then pre-annealing may proceed at a longer time, generally longer than 20 minutes
