Title: Manufacture of insulated gate fet
Inventor: MIWA YUKINOBU
IPC: H01L29/78
Filed: 1982-06-11
Abstract: PURPOSE:To prevent the production of an overhang at the end of a silicon layer and the decrease of the density of a source diffused layer by covering a main surface of a silicon substrate with a polycrystalline silicon layer, on which an impurity for forming a source region is doped, diffusing the impurity to form a source, and then oxidizing the polycrystalline silicon layer to form an insulating layer. CONSTITUTION:A polycrystalline silicon layer 11, on which boron (phosphorus or arsenic in N-channel) is doped, is covered on a P type impurity source and is thermally diffused, to form a channel part 5 and a source region 6. The layer 11 covered as an impurity diffusion source is all formed into an oxidized silicon layer 12, a thick oxidized silicon layer is covered on the surface including a gate 3 to form a surface protecting oxidized silicon layer, and a hole is opened by photoetching. Since the impurity-doped polycrystalline silicon layer is not washed, the end of the polycrystalline silicon gate does not make an overhang, and the electric leakage at the element can be reduced, thereby improving the reliability.

Abstract: PURPOSE:To obtain a foam free of frothy voids and excellent in low-temperature strengths and heat-insulating property, by using a polyol, a polyisocyanate, a catalyst, a foam stabilizer and a specified blowing agent. CONSTITUTION:In the production of a foam from a polyol, a polyisocyanate, a catalyst, a foam stabilizer and an blowing agent, a mixture obtained by mixing monobromomonochlorodifluoromethane with dibromotetrafluoroethane at a weight ratio of 52:48-95:5 is used as said blowing agent. When the amount of monobromomonochlorodifluoromethane used is 50wt.% or below based on the total blowing agent, the expansion ratio of the foam decreases and its low-temperature stability is worsened. When the amount of monobromomonochlorodifluoromethane used is above 95wt.% based on the total blowing agent, the cells of the foam become large and the heat-insulating property is decreased.
