Abstract: PURPOSE:To prevent the electric short circuit of a first polycrystalline silicon film and second polycrystalline silicon films and to prevent the short circuits between the second polycrystallaine silicon wiring circuits, by improving the shape of the side surface of the first polycrystalline silicon film. CONSTITUTION:A light sensitive resin is made to remain so that a desired pattern is formed by a conventional manufacturing method. With the patterned light sensitive resin 6 as a mask, first polycrystalline silicon film 5 is etched, and the light sensitive resin 6 is removed. Then, with the first polycrystalline silicon film 5 as a mask, etching is performed excessively so that an etched film 4 becomes concave-shaped. Thereafter, a polycrystalline silicon film 11, which is thinner than the first polycrystalline silicon film 5, is deposited. Then the polycrystalline silicon film 11 and the surface layer of the polycrystalline silicon film are oxidized, and a polycrystalline silicon oxide film 12 is formed on the entire surface. Then, the entire surface of the polycrystalline oxide film 12 is etched, and the polycrystalline silicon oxide film 12' at a part, where the first polycrystalline silicon film 5 is not present, is removed. Thereafter, the device is manufactured by the conventional method.

Title: Production of compound semiconductor crystal and crucible therefor
Inventor: KAWASE TOMOHIRO
IPC: H01L21/208
Filed: 1995-03-13
Abstract: PURPOSE:To prolong the life of crucible and improve the yield of a single crystal by forming a B2O3-containing layer on the surface of a crucible, putting a molten liquid into the crucible and solidifying the molten liquid from an end of the crucible to effect the growth of a compound semiconductor crystal. CONSTITUTION:A layer containing boron or a boron compound is formed on the surface of a crucible and the layer is heat-treated to form a layer containing boron oxide on at least the surface of the layer. A raw material (e.g. polycrystalline GaAs raw material) is charged into the crucible and melted by heating to form a molten liquid. The molten liquid is solidified from an end of the crucible to effect the growth of a crystal and obtain a compound semiconductor crystal (e.g. GaAs single crystal). The oxidation of the crucible can be prevented by this process to prolong the crucible life. The wetting of the molten liquid of the raw material to the crucible is prevented to suppress the generation of polycrystals.
