Title: Mos semiconductor device thereof and manufacture
Inventor: KONO TOSHIMICHI
IPC: H01L29/78
Filed: 1990-07-20
Abstract: PURPOSE:To control a size of a step part to extremely reduce a gate width and to prevent dispersion in dimensions of the gate width by forming a gate electrode in a wall side of the step part formed on a surface of a semiconductor substrate. CONSTITUTION:After an exposed silicon substrate 1 is thermally oxidized and a heat oxide film 2a is formed thereon, a polycrystalline silicon film 4 is formed all over. In the process, the polycrystalline film 4 is also applied to a wall side of a step part through the heat oxide film 2a. Then, the polycrystalline silicon film 4 is etched using a nitride film 3 as a mask to selectively remove the polycrystalline silicon film 4 in a part which is not coated with the nitride film 3. Thereby, a gate electrode consisting of the polycrystalline silicon film 4 is pattern-formed in a wall side of the step part. Since the gate electrode is formed in the wall side of the step part on a surface of the silicon substrate 1, a gate width of the step part can be formed to an extremely small size by controlling a size of the step part. Furthermore, since a size of the step part can be controlled at high precision, dispersion in gate width sizes can be prevented.

Title: Semiconductor element
Inventor: SUGIURA HIDEO
IPC: H01L31/04
Filed: 1987-08-03
Abstract: PURPOSE:To prevent the property of a p-n junction from the heat deterioration so as to increase a tunnel peak current by a method wherein either a p-type layer or an n-type layer, which compose a p-n tunnel junction layer, is made to be higher in dopant concentration at the p-n junction interface. CONSTITUTION:A large amount of dopant is doped into the tunnel junction interface 9 in a p-type layer of a tunnel junction layer 3 higher than the p-type layer. As a result, the diffusion takes place due to the heat treatment, but the dopant concentration of the junction interface 9 is made to be substantially high as the population of dopant is large which is formed through doping in quality. By these processes, the dopant is restrained from diffusing so as to prevent the property of the tunnel junction from the heat deterioration and the diffusion of dopant due to the heat treatment can be restrained, so that a peak current of a tunnel diode can be made to be larger.
