Abstract: PURPOSE:To prevent recording characteristics from being deteriorated due to oxidation, corrosion or the like, by providing a layer of a high molecular weight substance containing a crystalline thermoplastic resin, on a light-reflective layer. CONSTITUTION:A rewritable optical recording medium 11 comprises a high molecular weight substance 16 comprising a crystalline thermoplastic resin 14 and a noncrystalline thermoplastic resin 15, on a light-reflective layer 12 provided on a base 13.

Abstract: PURPOSE:To prevent a decrease in adhesive strength between a substrate and a supporting plate, by coating a side face of a GaAs substrate with an insulating film. CONSTITUTION:A high-frequency, high-output FET, a gate electrode 2, a source electrode 3, and a drain electrode 4 are formed on a semi-insulating substrate l and they are coated with an insulating film.
