The portion of the terminal 11 is more preferably a quadrangular shape or a circular shape having an area larger than that of the connection line 13 in order to facilitate connection with a terminal portion of another electronic device.
 図4は、他の実施形態の説明図である。 FIG. 4 is an explanatory diagram of another embodiment.
 基礎板21は、図1のように正方形である必然性はなく、図2のように長方形であってよい。
 さらに、L字型、円形、楕円形、星型、であってよい。さらに、それ以外の、どのような形状であってもよい。
The base plate 21 is not necessarily square as shown in FIG. 1, but may be rectangular as shown in FIG.
Furthermore, it may be L-shaped, circular, elliptical, or star-shaped. Further, any other shape may be used.
 図5は、さらに他の実施形態の説明図である。 FIG. 5 is an explanatory diagram of still another embodiment.
 印刷基板1の接続線13(端子11)及びニス部31の印刷回数は、1回に限定する必要はなく、図5のように複数回、上に重ねて印刷(積層印刷)することも可能である。
 また、基礎板21の表側だけではなく、裏側にも印刷して形成することが可能である。
 ここで、表側及び裏側の両方に印刷する場合であっても、複数回、さらに積層印刷することも可能である。
The number of times of printing the connection line 13 (terminal 11) and the varnish portion 31 of the printed circuit board 1 is not limited to one, and it is also possible to perform printing (stacked printing) on top of each other multiple times as shown in FIG. It is.
Moreover, it is possible to print and form not only on the front side of the base plate 21 but also on the back side.
Here, even in the case of printing on both the front side and the back side, it is also possible to perform multilayer printing a plurality of times.
 図6は、図5のさらなる発展形である。 6 is a further development of FIG.
 図6の様に、2色オフセット印刷を同じ面に何度も印刷することも容易である。
 さらに、同時に、裏面にも複数層印刷することが可能である。
 これによって、現在の半導体チップの製造方法においては、形成する層の限界を超えて、論理的にどれだけでも多くの層を作り出して、複雑な半導体回路を形成することが可能となる。
As shown in FIG. 6, it is easy to print two-color offset printing repeatedly on the same surface.
At the same time, multiple layers can be printed on the back surface.
As a result, in the current semiconductor chip manufacturing method, it is possible to form a complex semiconductor circuit by creating any number of logical layers beyond the limit of the layers to be formed.
 図7は、印刷基板1の製造方法の説明図である。 FIG. 7 is an explanatory diagram of a method for manufacturing the printed circuit board 1.
 図7(a)のような、可撓性かつ絶縁性の基礎板21に対して下記のように印刷をする。
 なおここで使用するのは、2色刷り用のオフセット印刷の機械を使用している。
 次に、伝導性(可撓性)のインクで、所定の位置に印刷を行う、第1印刷工程によって、図7(b)のように形成する。
 さらに、絶縁性(可撓性)のニスで、所定の位置に印刷を行う、第2印刷工程によって、図7(c)のように形成する。
 以上の様な工程を最低1回経ることによって、印刷基板1が製造される。
 これまでの説明では、2色刷りのものを念頭に説明してきたが、当然であるが、4色刷りの印刷機も多数存在する。さらに、それ以上のものも存在する。したがって、一回の印刷によって、以上の説明以上の複雑な回路を形成することが可能である。
 また、1度印刷したものに上書き印刷や、反対面に印刷することによって、より複雑な回路を形成することも可能である。
Printing is performed on the flexible and insulating base plate 21 as shown in FIG.
In this case, an offset printing machine for two-color printing is used.
Next, as shown in FIG. 7B, a first printing process is performed in which printing is performed at a predetermined position with conductive (flexible) ink.
Furthermore, it forms like FIG.7 (c) by the 2nd printing process which prints in a predetermined position with an insulating (flexible) varnish.
The printed circuit board 1 is manufactured by passing through the above processes at least once.
In the description so far, the description has been made with the two-color printing in mind, but of course, there are many four-color printing machines. There are more than that. Therefore, it is possible to form a complicated circuit more than the above description by one printing.
It is also possible to form a more complicated circuit by performing overprinting on what has been printed once or printing on the opposite side.
 図8は、より複雑な回路の例の説明図である。 FIG. 8 is an explanatory diagram of an example of a more complicated circuit.
 この回路は、N型MOSFETの回路を本実施形態の印刷によって形成する例である。このような比較的複雑な回路であっても、印刷によって形成することが可能である。
 製造方法の一例として以下の手順で作成する。
 (1)可撓性かつ絶縁性の基礎板21(紙又はプラスチック製のフィルム)上に、N型半導体の性質(可撓性の性質もあるとより可)を持ったN型半導体インク101を2か所印刷する(それぞれ、ソースとドレインの役割)。
 (2)(1)の2か所のN型半導体インク101に掛け渡すように、P型の半導体の性質(可撓性の性質もあるとより可)を持ったP型半導体インク102を印刷する。
 (3)(1)の2か所のN型半導体インク101にそれぞれ端子11(接続線13)が接続するように印刷する。
 (4)少なくとも、P型半導体インク102上を覆うように、絶縁性のニス部31を印刷する。
 (5)(4)のニス部31上に端子11(接続線13)を印刷する(ゲートの役割)。
 (6)(1)~(5)までの各印刷を覆うように、絶縁性のニスを印刷する。
 このように6回の印刷(2色刷りなら3回の印刷機を通す作業、3色刷りなら2回の印刷機を通す作業)で、比較的複雑なN型MOSFETを形成できる。
 同様にして、このN型MOSFETよりも複雑な回路も形成できる。
 また、より単純な回路であれば、少ない印刷工程で製造することができる。
This circuit is an example in which an N-type MOSFET circuit is formed by printing of the present embodiment. Even such a relatively complex circuit can be formed by printing.
As an example of the manufacturing method, it is created by the following procedure.
(1) An N-type semiconductor ink 101 having the properties of an N-type semiconductor (may be more flexible) on a flexible and insulating base plate 21 (paper or plastic film). Print two places (role of source and drain, respectively).
(2) Print P-type semiconductor ink 102 having P-type semiconductor properties (may be more flexible) so as to span the two N-type semiconductor inks 101 in (1) To do.
(3) Printing is performed so that the terminals 11 (connection lines 13) are connected to the two N-type semiconductor inks 101 in (1).
(4) The insulating varnish portion 31 is printed so as to cover at least the P-type semiconductor ink 102.
(5) The terminal 11 (connection line 13) is printed on the varnish portion 31 of (4) (role of the gate).
(6) An insulating varnish is printed so as to cover each printing from (1) to (5).
In this way, a relatively complicated N-type MOSFET can be formed by six times of printing (a work of passing three printing machines for two-color printing and a two-time printing machine of three-color printing).
Similarly, a circuit more complicated than this N-type MOSFET can be formed.
In addition, a simpler circuit can be manufactured with fewer printing steps.
 ここで、オフセット印刷の利点を説明する。
 一般にオフセット印刷(オンデマンド印刷)は、安価かつ高速であるため、極めて安価に大量に印刷基板を製造することができる。
 また、オフセット印刷は、2色刷りが可能な機械が多いため、そのまま、前述の第1印刷工程及び第2印刷工程の両方を1度で行うことができる。
 また、オフセット印刷(オンデマンド印刷)は、単なる印刷であるため、複雑な形状の回路を形成することも可能である。
 最後に、オフセット印刷の機械は、通常、本・パンフレット等を印刷している。
 しかし、オフセット印刷の機械は、高速であるがゆえに、その稼働率を上げることが難しい。
 しかし、本発明によると、本・パンフレット等を印刷していない空いた時間に、その空いた時間に回路基板を印刷することができ、設備の有効利用に資することが可能である。
Here, advantages of offset printing will be described.
In general, offset printing (on-demand printing) is inexpensive and high-speed, so that a large number of printed boards can be manufactured at a very low cost.
Moreover, since there are many machines that can perform two-color printing in offset printing, both the first printing process and the second printing process described above can be performed at once.
Moreover, since offset printing (on-demand printing) is simply printing, it is possible to form a circuit having a complicated shape.
Finally, offset printing machines usually print books, pamphlets and the like.
However, since the offset printing machine is high speed, it is difficult to increase its operating rate.
However, according to the present invention, it is possible to print the circuit board at the vacant time when the book / brochure is not printed, which contributes to the effective use of the equipment.
 以上の様な方法で形成された、印刷基板1は、低コストで、期間が短く、製造することができる。
 また、どのような形状であっても印刷が可能なので、小型化することも、軽量化することもできる。
 なお、上記記載はオフセット印刷に限定する趣旨ではない。どのような印刷機械を使用してもよい。
 また、ニス部31も別にニスに限定する趣旨ではなく、絶縁性かつ可撓性を有しており、印刷に適するものであればどのようなものであってもよい。
The printed substrate 1 formed by the method as described above can be manufactured at a low cost and with a short period.
Further, since printing is possible in any shape, it is possible to reduce the size and the weight.
Note that the above description is not limited to offset printing. Any printing machine may be used.
Further, the varnish portion 31 is not limited to varnish, but may be any material as long as it has insulating properties and flexibility and is suitable for printing.
 図9は、発展形の説明図である。 FIG. 9 is an explanatory diagram of the developed form.
 現在、半導体の回路は、より微細化を進めてきている。
 しかし、微細化はここにきて、その微細化速度は遅くなってきている。その理由は、数々あるが、半導体製造時に使用する光の波長の限界がその主な原因となっている。
 また、シリコンのウェハーの大きさの制限があり、それ以上の大きな半導体がつくれないという事情もあり、さらに、ウェハー全部を使うような、半導体は高額化する、実装することが困難であるなどが理由である。
 そこで、本実施形態は、発想を逆転させて、極めて大きな面に回路を形成するというものである。
 具体的には、例えば、図9(a)のように、B0サイズ(1031×1456mm)の紙全体に半導体回路を製造(印刷)する。
 B0サイズは、16枚のB5サイズの回路分の面積を有している。
 このような、回路の面積は、従来の半導体のサイズに比して極めて大きく、たとえ従来の半導体の製造に比して、微細化の程度が低い場合であっても、沢山の回路を製造できる。
 もちろん、印刷技術は日々進化しており、かなり微細な印刷も可能となってきている。
 もし、従来のウェハー上に形成しているものと同様の微細化を行った場合には、その実装可能な半導体の量は極めて大きくすることが可能である。
 また、この例では、B0の大きさまでであるが、さらに大きいものが印刷可能な印刷機械も存在するため、より大きな印刷による印刷基板1を形成することができる。
 また、印刷基板1は、可撓性を有していること、また、その表面はニス部31によって絶縁性を有しているため、図9(b)の様に、折りたたむことが可能である。
 そのため、広い面積の回路基板を形成しても、コンパクトにすることが可能である。
 また、可撓性が有るため、比較的取り回しが簡単(精密でなくてもよい)という効果もある。
Currently, semiconductor circuits are being further miniaturized.
However, miniaturization has come here, and the speed of miniaturization has become slower. There are a number of reasons for this, but the main reason is the limit of the wavelength of light used during semiconductor manufacturing.
In addition, there are restrictions on the size of silicon wafers, and there is a situation that larger semiconductors cannot be made. Furthermore, such as using the whole wafer, the semiconductor is expensive, and it is difficult to mount. That is why.
Therefore, the present embodiment reverses the idea and forms a circuit on a very large surface.
Specifically, for example, as shown in FIG. 9A, a semiconductor circuit is manufactured (printed) on the entire B0 size (1031 × 1456 mm) paper.
The B0 size has an area corresponding to 16 B5 size circuits.
Such a circuit area is very large compared to the size of a conventional semiconductor, and many circuits can be manufactured even if the degree of miniaturization is low compared to the manufacturing of a conventional semiconductor. .
Of course, printing technology is evolving day by day, and quite fine printing is possible.
If miniaturization similar to that formed on a conventional wafer is performed, the amount of semiconductor that can be mounted can be made extremely large.
In this example, although there is a printing machine that can print a larger one up to the size of B0, it is possible to form the printed substrate 1 by larger printing.
Moreover, since the printed circuit board 1 has flexibility, and the surface has insulation by the varnish part 31, it can be folded like FIG.9 (b). .
Therefore, even if a circuit board having a large area is formed, it can be made compact.
Further, since it is flexible, there is an effect that it is relatively easy to handle (it may not be precise).
 そして、図9(b)のように、折りたたんだ場合には、その一番外側に来る部分に、端子11(接続線13)がくるように製造する。
 これによって、印刷基板1と外部とを電気的に接続することが可能となる。
And when it folds like FIG.9 (b), it manufactures so that the terminal 11 (connection line 13) may come in the part which comes to the outermost part.
As a result, the printed board 1 can be electrically connected to the outside.
 図10は、基礎板21の両面に回路を形成する場合のより好適な例の説明図である。 FIG. 10 is an explanatory diagram of a more preferable example when circuits are formed on both surfaces of the base plate 21.
 例えば、図6では基礎板21の両面に回路を形成していた。
 しかしながら、上述のような製造方法では、基礎板21の両側の回路の間を微細に接続することは困難であった。
 そこで、図10では、基礎板21に図10(a)のように貫通孔41を形成する。
 その上に、接続線13又は端子11を形成することによって、基礎板21の両側の回路の間を微細に接続することができる。
 もちろん、この貫通孔41は、微細に大量に前もって形成しておくことが可能である。
For example, in FIG. 6, circuits are formed on both sides of the base plate 21.
However, in the manufacturing method as described above, it is difficult to finely connect the circuits on both sides of the base plate 21.
Therefore, in FIG. 10, the through hole 41 is formed in the base plate 21 as shown in FIG.
By forming the connection line 13 or the terminal 11 thereon, the circuits on both sides of the base plate 21 can be finely connected.
Of course, the through-hole 41 can be formed in advance in a minute and large amount.
 図11は、図9のような大きな基礎板21を折りたたんだ際に、その、面同士の回路を途中で接続する方法の説明図である。 FIG. 11 is an explanatory diagram of a method of connecting the circuits between the faces halfway when the large base plate 21 as shown in FIG. 9 is folded.
 図9のように、折りたたんだ場合、形成されたそれぞれの面は、折りたたんだ折り目部分で他の面に対して接続はされているが、広い面積に回路を形成するため、配線の距離が長くなってしまうこと(回路が複雑化すること)が懸念される。
 そこで、図11(a)のように、折りたたんで形成されるそれぞれの面(第1面121a、第2面121b)に、端子11(第1端子11a、第2端子11b、第3端子11c、第4端子11d)を形成する。
 その端子を折りたたんだ際に接触(第1端子11aと第2端子11b、第3端子11cと第4端子11d)させることによって、ショートカットが可能である。
As shown in FIG. 9, when folded, each formed surface is connected to the other surface at the folded crease part, but since the circuit is formed in a large area, the wiring distance is long. There is a concern that it will become complicated (the circuit becomes complicated).
Therefore, as shown in FIG. 11A, terminals 11 (first terminal 11a, second terminal 11b, third terminal 11c, and so on) are formed on the respective surfaces (first surface 121a, second surface 121b) formed by folding. A fourth terminal 11d) is formed.
When the terminals are folded, a shortcut can be made by bringing them into contact (first terminal 11a and second terminal 11b, third terminal 11c and fourth terminal 11d).
 図11(c)を用いて、端子11の接続方法を説明する。
 第1面121aに第1端子11aが形成されている。また、第2面121bに第2端子11bが形成されている。
 そして、第2端子11bの表面側に、可撓性、導電性かつ粘着性を有する導電接着部132を印刷する。
 他の部分には、可撓性、絶縁性かつ粘着性を有する非導電接着部131を印刷する。
 その状態で、第1面121aと第2面121bを折りたたむ、このようにしてショート化とした接続部を形成することが可能である。
A method for connecting the terminals 11 will be described with reference to FIG.
A first terminal 11a is formed on the first surface 121a. A second terminal 11b is formed on the second surface 121b.
And the conductive adhesion part 132 which has flexibility, electroconductivity, and adhesiveness is printed on the surface side of the 2nd terminal 11b.
On the other part, a non-conductive adhesive part 131 having flexibility, insulation and adhesiveness is printed.
In this state, it is possible to fold the first surface 121a and the second surface 121b, thus forming a shorted connection portion.
 図12は、ディスプレイなどを製造する方法の例である。 FIG. 12 shows an example of a method for manufacturing a display or the like.
 図12(a)の様に、それぞれの面にRed色用の回路、Green色用の回路、Blue色用の回路及び前述のRGBを制御する制御回路を印刷によって形成する。
 それを図2(b)のように、折りたたむことによって、ディスプレイを形成することも可能である。
 なお、この場合は、基礎板21は透明である必要がある。
As shown in FIG. 12A, a Red color circuit, a Green color circuit, a Blue color circuit, and the above-described control circuit for controlling RGB are formed on each surface by printing.
It is also possible to form a display by folding it as shown in FIG.
In this case, the base plate 21 needs to be transparent.
 前述の例では、折りたたむことのみを記載してきたが、別々の印刷した印刷回路を複数枚、次次に単に重ね、図11と同様の方法によって、大きな回路を作ることも可能である。この場合、重ねる枚数は極めて多くすることが可能であり、より大きな回路を形成することも可能である。少なくとも、3枚以上、可能であれば、5枚以上によって形成することが、より大面積かつ複雑な回路を作れるという点で好適である。 In the above example, only folding has been described, but it is also possible to make a large circuit by a method similar to that shown in FIG. In this case, the number of stacked sheets can be extremely large, and a larger circuit can be formed. Forming at least 3 or more, and if possible, 5 or more is preferable in that a large area and a complicated circuit can be formed.
 また、本実施形態の方法は、基礎板21は可撓性を有する。また、印刷するインク(導電性、半導体、非導電性)も、可撓性を有している。
 そのため、印刷基板1自体も、可撓性を有することになる。そのため、折り曲げ、緩やかなカーブ、なども可能である。
 また、基礎板21の形状も単に印刷できれば足りることから、従来の四角だけではなく、様々な形状を作成できる。
 複数積層する場合は、積層する個々の印刷基板1の形状を徐々に変化させることによって、あたかも3Dプリンタが作るような、複雑な形状の印刷基板1を製造することも可能である。これにより、回路としての利用に加えて、オブジェという側面での利用や、例えばパソコンの外観も兼ねた利用も可能である。
 基礎板21の大きさは、B0だけではなく、A0、B1、A1であってもよく、それ以上の大きさであっても、逆に、それ以下の大きさのものであってもよい。
 また、本実施形態の印刷基板1は、大面積とできるので、大きく巻き数の多いコイルを形成することも可能である。この場合、非接触式の電源供給などには特に大きな効果を発揮すると思われる。電源ケーブルを不要とするシステムの構築にも役に立つと思われる。
 また、非接触式の電源供給でICの駆動する例えば、非接触型ICカードシステムにも利用が可能となると思われる。
In the method of the present embodiment, the base plate 21 has flexibility. Further, the ink to be printed (conductive, semiconductor, non-conductive) is also flexible.
Therefore, the printed board 1 itself has flexibility. Therefore, bending, a gentle curve, etc. are possible.
In addition, since it is sufficient that the shape of the base plate 21 can be simply printed, various shapes can be created in addition to the conventional square.
In the case of stacking a plurality of layers, it is possible to manufacture a printed substrate 1 having a complicated shape as if a 3D printer is produced by gradually changing the shape of each printed substrate 1 to be stacked. Thereby, in addition to the use as a circuit, it can be used in the aspect of an object, for example, the appearance of a personal computer.
The size of the base plate 21 may be not only B0 but also A0, B1, and A1, and may be larger than that, or conversely, may be smaller than that.
Moreover, since the printed circuit board 1 of this embodiment can be made into a large area, it is also possible to form a coil with a large number of windings. In this case, it is considered that the present invention is particularly effective for non-contact type power supply. It is also useful for building a system that does not require a power cable.
Also, it can be used for, for example, a non-contact type IC card system in which an IC is driven by a non-contact type power supply.
 印刷方法は、オフセット印刷を念頭に記載したが、インクジェット方式、レーザプリント方式でも同様のことが可能である。 The printing method is described with offset printing in mind, but the same is possible with the ink jet method and the laser printing method.
 基礎板21は、紙に限定されない。特に、絶縁性のフィルム等を利用することも可能である。
 もっとも、折りたたんだ際などに、断線を防ぐためにある程度インクが浸透する材質であるとより好適である。
The base plate 21 is not limited to paper. In particular, an insulating film or the like can be used.
However, it is more preferable to use a material that allows ink to penetrate to some extent in order to prevent disconnection when folded.
 好適には、印刷は、2色刷オフセット印刷を用いる。
 このような構成を有することから、一度に、接続線13(端子11)とそのコーティングであるニス部31を印刷できるからである。
 また、2色刷オフセット印刷の機械は比較的多く、印刷業者に存在し、空いている時間が長い傾向があるからである。
Preferably, printing uses two-color offset printing.
Because it has such a configuration, the connection line 13 (terminal 11) and the varnish portion 31 that is the coating can be printed at a time.
This is also because there are relatively many machines for two-color offset printing, and they exist in printers and tend to have a long free time.
 好適には、前記絶縁性のあるニスは、静電気を防止する材質を用いる。
 このような構成を有することから、静電気を防止することが可能となっている。
Preferably, the insulating varnish uses a material that prevents static electricity.
With such a configuration, it is possible to prevent static electricity.
 本実施形態の方法は、コンピュータ、半導体素子機能を有した基板(回路)、配線、ディスプレイ、キーボード、その他の入力装置等を作成できる。
 本実施形態の方法によって、短納期、省電力化が可能となる。
 また、その他の、スマートフォン、テレビ、その他の電化製品にも使用できる。
 さらには、基本が、紙(プラスチック)のシートであるので、机、テーブル、柱、本棚、その他の家具を紙(プラスチック)を重ねることによって形成することも可能である。
 つまり、本発明のさらなる本質は、半導体回路が構造体を兼ねることができるということである。なお、そのためには、複数枚のシートを重ねる際に接着剤によって結合させることが好適である。
 また、2色刷りのオフセット印刷に限る趣旨ではなく、多色刷りの印刷のほうがより好適である。もっとも、コスト・精密さの点で多色の方が一方的に有利とは限らず、色数が少ない場合が最適とはいえない。
The method of this embodiment can create a computer, a substrate (circuit) having a semiconductor element function, wiring, a display, a keyboard, other input devices, and the like.
By the method of this embodiment, a short delivery time and power saving can be achieved.
It can also be used for other smartphones, TVs, and other electrical appliances.
Furthermore, since the basis is a sheet of paper (plastic), a desk, a table, a pillar, a bookshelf, and other furniture can be formed by stacking paper (plastic).
That is, a further essence of the present invention is that the semiconductor circuit can also serve as a structure. For this purpose, it is preferable to bond a plurality of sheets with an adhesive when they are stacked.
Also, the purpose is not limited to two-color offset printing, and multi-color printing is more preferable. However, in terms of cost and precision, multiple colors are not necessarily unilaterally advantageous, and the case where the number of colors is small is not optimal.
<実施形態の構成及び効果>

 このような構成を有することから、印刷用の印刷装置でプリント基板を製造することが可能となっている。
