Title: Partial dry plating method
Inventor: IMAI KIYOHIRO
IPC: C23C30/00
Filed: 1987-10-30
Abstract: PURPOSE:To obtain a part of the high ornamental value having the dry plating to prescribed selective parts or the two colors of the surface color of a substrate and the dry plating color by using a black chrome plating layer or black ruthenium layer for a partial mask to be used at the time of dry plating. CONSTITUTION:An org. resist 3 is previously coated to the prescribed part and after the resist is cured by baking, the wet plating films 4, 9 of the black chrome plating or black ruthenium plating are coated thereon. The org. resist 3 is then dissolved away by an org. solvent to form the substrate surface having the substrate color and the wet plating color; thereafter, the dry plating layer is formed on the surface and the wet plating film is stripped away. The overetching under the resist film and the exfoliation of the resist film or the generation of the interference color of the dry plating layer by the heat generated at the time of the dry plating and the decoloration of the substrate surface by the thermal diffusion of the substrate surface and the plating film for masking are, therefore, prevented and the parts of the high ornamental value having the dry plating to the prescribed selective parts or the two colors of the surface color of the substrate and the dry plating color are thus inexpensively obtd.

Abstract: PROBLEM TO BE SOLVED: To suppress the generation of hot carriers by relieving an electric field near a gate electrode by forming a diffusion area having the same conductivity as that of a drain area and sufficiently low impurity concentration or a diffusion area having the opposite conductivity on the surface of a low- concentration area forming the drain area. SOLUTION: A photoresist 3 is formed on a gate oxide film 2 so as to open the area proposed for the formation of the low-concentration diffusion area of a drain area. In order to form, for example, a low-concentration N-type diffusion area on the surface of a P-type semiconductor area l by using the photoresist 3 as a mask, the ion of an N-type impurity, for example, phosphorus is implanted. Thereafter, the ion of a P-type impurity, for example, BF2 is implanted by utilizing the same mask. The P-type impurity is prepared by selecting an impurity combination which is less diffused than the N-type impurity. When thermal diffusion is performed in the succeeding process, therefore, a P-type impurity area 12 is formed in a state where the area 12 is surrounded by a low-concentration N-type diffusion area 4.
