Title: Coating liquid for insulating-film formation use, semiconductor device using it and its manufacture
Inventor: SUGIMURA MASAHIKO
IPC: H01L21/312
Filed: 1990-09-26
Abstract: PURPOSE:To obtain a coating liquid whose etch rate is about the same as that of a thermal oxide film, whose permittivity is low and which forms a high-safety insulating film by a method wherein a siloxane-based prepolymer is mixed with hydrocarboxic acid esters. CONSTITUTION:A siloxane prepolymer is obtained by hydrolyzing and condensation-polymerizing at least one kind of alkoxysilane selected out of alkoxysilanes expressed by general formulas: Si(OR<1>)4, R<2>Si(OR<3>)3 and R<4>R<5>Si(OR<6>)2. (Where R<1> to R<6> represent a 1 to 6C alkyl group or a 6 to 10C aryl group and they can be the same or different from each other.) The condensation- polymerization reaction of the alkoxysilane is executed generally under the existence of an acid catalyst or an alkali catalyst and water. Its reaction temperature is at 0-100 deg.C. Especially, lactic acid methyl or lactic acid ethyl is preferable as the hydrocarboxic acid esters. The siloxane-based prepolymer is mixed with the hydrocarboxic acid esters to form a coating liquid. The coating liquid is coated on a substrate by an ordinary coating method such as a spin coating method; after that, its solvent is heated and dried. After that, a heat treatment is executed; a thermoset film is formed.

Filed: 1986-10-28
Abstract: PURPOSE:To obtain stable laser output beams even at a pulseoperating time by connecting in parallel an auxiliary power source to a power source that is connected to a cathode and an anode. CONSTITUTION:A main power source 1 and an auxiliary power source 20 are connected in parallel to a cathode 11 and an anode 12 through a cable 14.
