IPC: H01L21/336
Filed: 1993-12-14
Abstract: PURPOSE:To prevent substrate surface from etching damage by a method wherein the center part of a polycrystalline silicon film is entirely changed to a silicon oxide film, the silicon oxide film is removed by etching, and a gap is formed on the center part of the polycrystalline silicon film. CONSTITUTION:After a photoresist 6 has been removed, all the polycrystalline silicon film 4 on the region other than that on the part under a silicon nitride film 5 is changed to a silicon oxide film 8. As a result, the polycrystalline silicon film 4 on the element formation region is divided into two parts. Then, the silicon nitride film 5 is etched, and the silicon oxide film 8 is etched. Subsequently, the arsenic doped in the polycrystalline silicon film 4 is thermally diffused into a silicon substrate 1, and an N-type impurity diffusion layer 11 is formed. At this time, a silicon oxide film 10 becomes the gate insulating film of a MOS transistor. The polycrystalline oxide film 10 is patterned by photolithography and anisotropic dry etching, and a gate electrode 13 is formed.

Title: Thermal transfer sheet and manufacture thereof
Inventor: OGAWA KEIICHI
IPC: B41J31/00
Filed: 1989-12-29
Abstract: PURPOSE:To obtain a thermal transfer sheet capable of imparting printing excellent in dry cleaning properties or ironing properties by forming an ink layer from an emulsion containing polyethylene wax having a high m.p. and a colorant. CONSTITUTION:A thermal transfer ink layer is formed from ink consisting of polyethylene wax and a colorant. Polyethylene wax has a softening point of 100 deg.C or higher and, when the softening point is less than 100 deg.C, formed printing is insufficient in dry cleaning properties or ironing properties. As the colorant, org. or inorg pigment having good characteristics as a recording material, for example, carbon black is pref. The emulsion ink used in the formation of the ink layer is prepared by mixing a commercial polyethylene wax emulsion and a commercial pigment dispersion. The advantage due to the emulsion resides in such a point that the excellent transfer ink layer is formed even when polyethylene wax to be used has a relatively high softening point.
