Filed: 1987-05-29
Abstract: PURPOSE:To prevent transversal oxidation (a bird' s beak) from being generated, by using masks of bilayer films for selective oxidation so as to pile a CVD silicon nitride film on a heat silicon nitride film. CONSTITUTION:A heat silicon nitride film 2 is formed on a surface of a silicon substrate 1. Subsequently, a CVD method is used to pile a silicon nitride film 3 on the heat silicon nitride film 2. The heat silicon nitride film 2 and the silicon nitride film 3 on a part for the formation of a selective oxidation film are selectively etched to be patterned. This mask is used to perform oxidation and to form the selective oxidation film 4. Since such bilayer films composed of the heat silicon nitride film, good in its adhesiveness to the silicon substrate, and the silicon nitride film, high in its oxidation-proof performance are used as masks, the selective oxidation film can be formed with few birds beaks.

CONSTITUTION:FFs 101, 102 and 103 are sequentially specified with an address coder 111. The FFs are initialized at '0,' '1' and '0.' Then, the FF 101 is specified with the coder 111 in order to change the state of the FF 101. As a scan data, '1' is inputted. When a clock pulse is applied to a first-phase scanning lock pin 17, a changing signal is inputted into a path under test 100. The FF 103 is specified with an address coder 112. A clock pulse is applied to a second phase scanning lock 18 so that system data are received after the elapse of the maximum propagation delay time allowed for the path 100 from the change in signal in the FF 101. When there is no defective propagation delay in the path 100, '1' is taken-in into the FF 103. When there is a defect, '0' is inputted therein. Finally, the state of the FF 103 is observed and judged.

Abstract: PURPOSE:To improve discharging property and preservability by adding magnesium oxide or titanium oxide and a paste into evaporated zinc powder in the half dried condition, and pouring electrolyte into the mixture to form a gel zinc negative electrode. CONSTITUTION:An alkali battery is made by placing in a vessel 1 a gel zinc negative electrode 5 together with a black mix body 2 containing silver oxide as a positive electrode active material. The gel zinc negative electrode is prepared by mixing magnesium oxide or titanium oxide and an alkali-resistant paste with evaporated zinc powder in the half dried condition which contains uniformly 0.05-3.0wt% of water, and pouring an alkali electrolyte therein. As adhesive strength between zinc powder and the paste is large, stable and uniform, gel form is obtained only by pouring alkali electrolyte. As the result, the gel zinc negative electrode can be efficiently scaled, and discharging property of a battery can be improved under a heavy load and at a low temperature.
