Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To reduce a dark current by installing an anode electrode constituted of metal having a high barrier to positive holes which metal is arranged on an insulating film having specified TeO2 component which film is formed on the surface of a compound semiconductor substrate whose main component is CdTe, and a cathode electrode constituted of metal having a high barrier to electrons which metal is arranged on the back of the board. SOLUTION: Both surfaces of a substrate which is composed of chlorine doped high resistance CdTe semiconductor single crystal and has face orientation (111) are ground. A worked denatured layer generated by polishing is eliminated by etching. After approximate metal Te layers wherein the ratio of Te is more excessive than that of Cd are formed on the surface and the back of the CdTe substrate, thermal oxidization is performed in oxygen atmosphere, and oxidized films wherein TeO2 component is 96% (higher than or equal to 90%) are formed. Indium is evaporated on the (111) B surface side of the substrate and turned into an anode electrode. Electroless plating of gold is performed on the (111) A surface side which is opposite to the indium electrode surface, and a cathode electrode is formed. Since the oxidized film wherein the ratio of Te is more excessive than that of Cd is formed on the interface between the anode electrode and the CdTe substrate, a dark current can be reduced on the anode electrode forming surface.

Abstract: PURPOSE:To decrease the number of input ports by selecting the content of an initial address register or the output of an arithmetic circuit and inputting the same to a pointer according to the result of the comparison of the output of the arithmetic circuit and the content of a final value address register and synthesizing voice signals. CONSTITUTION:The pointer 321 inputted with the content Q1 of the initial address register 140 reads out the top address P1 of divided voice data arrays to the pointer 350. A voice decoding circuit 370 synthesizes the voice signal in accordance with the voice data of one word instructed by the top address P1 and synthesizes the entire part of a sentence by successively repeating this operation. The arithmetic circuit 130 adds 1 to the content Q1 of the pointer 321 to make Q2. The Q2 is smaller as the result of the comparison of the result Q2 of computation and the final value address Q12 in a comparator circuit 160 and, therefore, a selection circuit 120 transfers the Q2 to the pointer 321 to synthesize the entire part of the sentence. One piece of the input pointer 110 is necessitated in this way and the number of the pointers is reduced.
