Title: Semiconductor device
Inventor: ABE YOSHIHIRO
IPC: H01L29/78
Filed: 1983-01-27
Abstract: PURPOSE:To block the transverse directional diffusion advancing downward of a gate from a source and a drain region and then inhibit punch through by boring a groove in the semiconductor layer between the source and the drain regions constituting an FET, and forming a gate electrode therein via an insulation layer. CONSTITUTION:Thick insulation oxide film 2 serving as the gate region and element isolation regions are formed by selective oxidation on the surface of a semiconductor substrate 1, and the film 2 of the gate region positioned at the center is removed by etching, thus generating the deep groove therein. Next, a thin insulation oxide film 3 for gate is adhered over the entire surface including said groove, and, by being positioned thereon, the gate electrode 4 composed of polycrystalline Si is formed on the groove. Thereafter, impurity ions are implanted through the film 3 positioned on both sides of said electrode, and accordingly the source and drain regions 5 are generated on the surface layer of the substrate 1 by self-alignment. Thus, the transverse directional diffusion of the region 5 is blocked, and at the same time the generation of punch through is eliminated.

Filed: 1981-01-30
Abstract: PURPOSE:To provide a silver oxide battery, which is prepared by using silver oxide as the positive active material, zinc as the negative active material and an aqueous caustic alkaline solution as the electrolyte, with a means of detecting its life by using a Zn-Hg-Sn-Pb alloy powder in preparing the negative mixture, and thereby reducing the self-discharge of the battery and decreasing the voltage of the battery gradually in the last stage of the discharge. CONSTITUTION:A positive mixture 2 principally consisting of silver oxide powder, a separator 3 and an electrolyte holding material 4 are placed in a positive can 1 also serving as a positive terminal. A negative mixture 5 prepared by gelling a Zn-Hg-Sn-Pb alloy powder is placed in a negative can 6 also serving as a negative terminal. An insulating gasket 7 is interposed between the cans 1 and 6.
