    摘要: A polyarylene sulfide resin composition comprising a resin composition obtainable by polymerizing 40 to 0.1 part by weight of an unsaturated polyester and 0.01 to 30 parts by weight of a monomer having one or more ethylenic unsaturated bonds in the presence of 100 parts by weight of a composition comprising 1 to 99 wt. % of a polyarylene sulfide resin and 99 to 1 wt. % of a thermoplastic polyester. Since the polyarylene sulfide resin composition of the present invention is in a state wherein the polyarylene sulfide resin and thermoplastic polyester are uniformly mixed, the constituent components are uniformly dispersed and mixed to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Consequently, the composition of the present invention is very superior in that the adhesive property of paint film (paintability), which the conventional polyarylene sulfide resins do not have well, has been improved without a large reduction in the excellent properties of the polyarylene sulfide resin.

    摘要: A semiconductor device is constructed so that an insulation film is provided in regions other than a protruding portion of a substrate. A polycrystalline silicon layer and a metal silicide layer are formed over said insulation film to provide a multi-layer structure, and a take-out portion for at least one of the emitter, base, and collector members of a bipolar transistor provided in the mesa region is constituted by a film of this multi-layer structure. By virtue of the use of metal silicide together with the polycrystalline silicon, a very low resistance is achieved which enhances the device's operating speed. Further, the metal silicide is separated from the protruding portion of the substrate by a portion of the polycrystalline silicon to provide a smooth interface with the substrate. This smooth interface significantly reduces crystal defects in the single crystal substrate.
