Title: Manufacture of thermoplastic resin sheet
Inventor: SAKAMOTO JUN
IPC: B29K67/00
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To obtain a product having an excellent productivity and quality with a simple facility by insulating a conductive portion of a surface of a charged roll from a core of the roll and manufacturing a cast sheet. SOLUTION: The sheet is directly charged, efficiently brought into close contact with a cooling medium, air entraining between the sheet and the medium or an instability of a bank mold is suppressed by the sheet sandwiched between the charged roll and the medium. A conductive portion of the surface of the charged roll is insulated from the core of the roll. In order to cool the surface of the roll even without passing an insulation refrigerant, the cooling medium used for the cooling medium is branched, guided to the charged roll to simplify an apparatus constitution and to simplify apparatus maintenance. If the charged roll and the cooling medium are discharged therebetween, only the conductive layer on the surface of the charged roll is damaged, but the surface of the charged roll is not largely roughed.  Adverse influence is not effected to the surface of the film, and the damage is limited only to the surface layer and the roll can easily be recycled. Thus, a casting speed can be accelerated, and the sheet of high quality can be manufactured with good productivity.

Abstract: PURPOSE:To make it possible to perform minute patterning of metal, by using a photoresist mask, which is formed on a polycrystalline semiconductor film that is formed on a metal film to a specified thickness, as a mask, and performing dry etching of the metal film. CONSTITUTION:A metal film 14 is formed on an insulating film 12 on a semiconductor substrate 10. On the film 14, a polysilicon film 16 is formed as a polycrystalline semiconductor film so that the reflectivity with respect to the exposure wavelength becomes approximately minimum. On the film 16, a photoresist film 18 corresponding to a desired wiring pattern is formed by a photolithography technology. At this time, the light reflection from the lower layer of the photoresist is suppressed in photoresist exposure. Thus, the photoresist pattern characterized by less dispersion in size and shape is obtained. With the photoresist film 18 as a mask, dry etching is performed, and a metal film 14A and a polysilicon film 16A are obtained. Thus, the metal film 14A, which has excellent fidelity to the wiring pattern, can be obtained.
