Abstract:
PROBLEM TO BE SOLVED: To provide a forming method of a metal thin film, capable of achieving refinement and high yield more than the past, without raising a resistance value of the thin film more than the necessity.SOLUTION: Electroless plating processing is applied to a substrate 40 to which ink 2A containing a catalyst material is transcribed. A metal thin film 42 is selectively formed to a transfer area of the ink 2A on the substrate 40. Moreover, ink 2 is transcribed by using a plate blanket 1, and the contact is done by pressure compression in a transfer process. Alignment becomes easy, and the pressure at the contact is made uniform as a whole, and the yield when the metal thin film 42 is formed improves. Moreover, not the material of the metal thin film 42 but the catalyst material of the electroless plating processing is included. A resistance value of the metal thin film 42 lowers compared with the past, and the refinement of the pattern becomes easy.

PROBLEM TO BE SOLVED: To provide a printing method by which a pattern can accurately be formed by a simple process. SOLUTION: An elimination plate 10 having a coarse surface 10A and a mirror surface 10B on the surface is brought into pressurization-contact with an ink 2 on a flat blanket 1. A section corresponding to the mirror surface 10B of the ink 2 is transferred to the elimination plate 10 and removed from the top of the flat blanket 1 by a difference in surface property, i.e., adhesion to the ink 2 between the coarse surface 10A and the mirror surface 10B of the elimination plate 10. On the flat blanket 1, a section corresponding to the coarse surface 10A remains, and the remaining section becomes a printing pattern layer 2B. By bringing a printed to be printed board 4 into pressurization-contact with the printing pattern layer 2B, the printing pattern layer 2B is transferred to the board to be printed 4.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing an electronic device, which can secure high performance of the electronic device, can reduce cost and can improve productivity. SOLUTION: A sacrificial layer 12 of MgO etc., is formed on a first substrate 11 and patterned, and a support layer 13 of SiO 2 etc., is formed. On the sacrificial layer 12, the electronic device 14 such as a TFT and a capacitor is formed with a support layer 13 interposed, and covered with a protective layer 15 of SiN x etc. The protective layer 15 and support layer 13 are partially removed to expose part of the sacrificial layer 12, which in turn is etched away. The electronic device 14 on the first substrate 11 is brought into contact with an adhesive layer 22 on a surface of a second substrate 21 and the first substrate 11 is separated to transfer the electronic device 14 to the second substrate 21. The electronic device 14 can be selectively transferred by a method of removing only the sacrificial layer 12 of the electronic device 14 to be transferred. COPYRIGHT: (C)2009,JPO&INPIT
