Title: Manufacture of semiconductor memory
Inventor: NAKAJIMA HIDEHARU
IPC: H01L21/8242
Filed: 1988-07-15
Abstract: PURPOSE:To prevent deterioration of coverage of an insulating film on a take- off electrode due to a steepness of difference in level by flattening the surface of the insulating film by a heat treatment. CONSTITUTION:An insulating film 14 protecting a take-off electrode is formed not of SiO2 but of an insulating film, which can flatten the surface by heat treatment such as PSG while later forming the insulating film 14 having the flat surface by heat treatment, Since thereafter the other electrodes 8a and 8b of the capacity elements 4a and 4b are formed, the insulating film 14 generates no valley-shaped part, which makes to generate an unexposed part of a resist so that the surface is flattened. Thereby, a problem, in which the electrodes 8a and 8b are short-circuited to a bit wire due to the residue of polycrystalline silicon generated under the unexposed part, can be evaded. Further, after forming the insulating film 14, the surface part of an SiN film 17 is oxidized by heat treatment to form an SiNOx film 18, an dielectric film can be stabilized.

Title: High temperature stabilization type embedding material
Inventor: OGINO HIROYA
IPC: B22D27/02
Filed: 1986-07-26
Abstract: PURPOSE:To eliminate long solidification time, surface roughness, poor fluidity, etc., by using an embedding material which consists of magnesia, zirconia, alumina magnesia alumina as aggegate and is added with the carboxylate of an alkali metal and alkaline earth metal. CONSTITUTION:The shrinkage of the aggregate consisting of 1 or >=2 kinds among the magnesia (MgO), zirconia (ZrO2), alumina (Al2O3) and magnesia alumina (MgO.Al2O3) by the solidification on drying during casting and by sintering is suppressed by the presence of at least 1 or >=2 kinds of the carboxylate of the alkali metal and carboxylate of the alkaline earth metal such as magnesium acetate and calcium acetate. An expansion is effected at the time of the crystal transformation of the embedding material if 1 or 2 kinds of crystobalite or colloidal silica are added to the above-mentioned embedding material. The difference between the shrinkage of the embedding material by calcination and the shrinkage of the metal is thus compensated.
