IPC: H01L29/861
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To keep a practical breakdown voltage between respective chips by making a groove of specified width when a P layer is divided on the anode side while leaving a common cathode thereby decreasing the width of the groove. SOLUTION: Grooves are made in an N type semiconductor with a width D1 for cutting a P layer and a glass layer excellent in electric insulation is formed on the surface of the groove and on the end face of a chip over the entire periphery thereof. Surface of an N layer functions as a common cathode K. Each metal electrode M bonded onto the surface of the P layer functions as an anode electrode and a linked diode chip is formed. When the interval D1 between respective diode chips is in the range of 400-600 μm, a breakdown voltage of 2000 V can be kept stably between the chips. More specifically, the size can be reduced keeping the practical breakdown voltage of 1000 V-2000 V stably by setting the width of the groove in the range of 200-600 μm.

Abstract: PURPOSE:To separate and remove ionic and colloidal actinide elements in a radioactive waste water by using a sandwich-shaped adsorptive filtration film composed of a laminar body of a specified thickness, which is made of tannin- fixed cellulose powder, and two sheets of filter paper, filtration membranes made of cellulose, which hold both faces of the laminar body. CONSTITUTION:An adsorptive filtration film is produced by forming tannin-fixed cellulose powder into a laminar body of 1 to 10mm in thickness and then by making two sheets of filter paper, filtration membranes made of cellulose, hold both faces of the laminar body. The tannin-fixed cellulose powder, which is a main constituent of this filtration film, is obtained by dipping cellulose powder in a solution of about 25% NaOH for about 30min so as to form alkali cellulose, then by bringing it into contact with epichlorohydrin, hexamethylenediamine and again epichlorohydrin in order for about 30 to 120min respectively, and finally by bringing it into contact with a tannin solution for about 2 to 24hr. As the tannin, both hydrolysis-type tannin and condensation-type tannin are usable. It is possible, by using this method, to give the film two functions, adsorptivity and filterability.
