Title: Analog-digital converter
Inventor: GOTOU ATSUE
IPC: H03M1/00
Filed: 1988-05-25
Abstract: PURPOSE:To stabilize the action of an analog comparator by branching a current supply channel from a chip terminal for supplying a current to an internal circuit into plural channels and making exclusive-use a pair of channels out of them for an analog comparator. CONSTITUTION:The converter provides a DA converter 11 to generate a reference voltage, an analog voltage comparator 12 to compare a reference voltage and an analog voltage input and a successive comparing register 14 to control the converter 11 and the comparator 12. In this constitution, since current supply channels 161 and 162 exclusive-use to the comparator 12 are separated from current supply terminals 151 and 152 to other current supply channel, it is hard to receive the influence of the switch noise due to the converter 11, etc., connected to other channel and the action of the comparator 12 is stably executed. Further, for channels 161 and 162, the wiring distance is smaller than other channel, the parasitic inductance becomes smaller, and therefore, the power source voltage fluctuation of the comparator 12 becomes smaller. Consequently, the stability of the action of the comparator 12 is improved for the fluctuation of the supply voltage.

IPC: H01G4/12
Filed: 1989-05-19
Abstract: PURPOSE:To obtain a small type grain boundary insulated type semiconductor porcelain capacitor of large capacitance by a method wherein, after diffusing substance has been thermally diffused into a semiconductor porcelain in a container which is depressed to less than atmospheric pressure, gas containing oxygen is introduced into the container, the pressure of the container is increased to atmospheric pressure or more by introducing oxygen-containing gas into the container, the container is cooled down and crystal boundary is reoxidated. CONSTITUTION:A semiconductor porcelain 4b and diffusing substance 5 are arranged in a container 1 which is evacuated to less than atmospheric pressure, and after thermal diffusion has been conducted by heating, the container is brought into atmospheric pressure or higher by introducing oxygen-containing gas into the container 1, and at the same time, the inside of the container 1 is reoxidated by cooling it down. When the semiconductor porcelain 4b and the diffusing substance 5 are heated up in the container which is evacuated to less than atmospheric pressure as above-mentioned, the quantity of the diffusing substance 5 adhered to the semiconductor porcelain 4b is increased, and the diffusion to the crystal boundary is accelerated. As a grain boundary layer is reoxidated subsequently, the excess reoxidation of the crystal grains in the vicinity of the surface of the semiconductor porcelain 4b can be prevented. As a result, a miniaturized grain boundary insulated type semiconductor porcelain capacitor of large capacitance, having a high dielectric breakdown voltage value, can be obtained.

Abstract: PURPOSE:To obtain a semiconductor device in which a stepped part can be covered satisfactorily by a method wherein, after a high melting point metal silicide film is formed by CVD, the silicide film is etched and left as a side wall and again a high melting point metal silicide film is laminated. CONSTITUTION:Gate insulating films 2 and 4 and polycrystalline Si layers 3 and 5 are formed on an Si substrate 1. A CVD-WSi2 film 20 with the thickness nearly equal to the thickness of the step in the polycrystalline Si layer 5 is deposited. A side wall 21 is formed by RIE. The WSi2 film 20 on the flat parts may be etched off completely or may be left a little. Therefore, the completion of etching can be controlled easily.
