Abstract: A method to provide an improved production yield of electronic devices. A thin film device 41 is manufactured by the following method. Semiconductor elements 11 are formed on the substrate 10. Then, a protective film is adhered onto the upper portions of the semiconductor elements 11 using an adhesive agent. Then, the substrate 10 is removed along the thickness direction from the surface thereof opposite to the surface having the semiconductor elements 11 provided thereon. Subsequently, a film 16 is adhered onto the surface of the removal-processed substrate 10. Subsequently, the protective film is removed. The obtained thin film device 41 is heat-treated.

Abstract: The present invention provides a process for continuously producing a polymer sheet having an excellent surface smoothness, an apparatus for producing such a polymer sheet, and an optical polymer sheet produced by such a process. The process for producing a polymer sheet comprises coating or laminating, on a polymer base sheet, an ultraviolet-curing resin composition, adhering the coated or laminated polymer base sheet to a member having a smooth surface whose maximum surface roughness (Rmax) satisfies Rmax≦0.1 &mgr;m, in a state that the ultraviolet-curing resin composition is soft, and applying an ultraviolet light to transfer smoothness of the smooth surface of the member onto the polymer base sheet.

Abstract: The present invention provides a material for electrical insulating organic film, superior in electrical properties, thermal properties and low water absorption; an electrical insulating organic film made from the material; and a process for production of the film. That is, the present invention provides an electrical insulating organic film having fine pores, consisting of a layer of a polybenzoxazole resin represented by the following general formula (1): wherein n is an integer of 2 to 1,000; X is a tetravalent organic group; and Y is a bivalent organic group; a material for electrical insulating organic film obtained by mixing a polybenzoxazole precursor or a polybenzoxazole resin, with an oligomer; and a material for electrical insulating organic film, obtained by reacting at least one carboxylic acid terminal of a polybenzoxazole precursor with an amino group- or hydroxyl group-containing oligomer.
