Title: Vapor growth method for compound semiconductor
Inventor: NAKADA HIROAKI
IPC: H01L21/205
Filed: 1987-04-24
Abstract: PURPOSE:To grow III-V compound semiconductor crystal of high purity with good controllability and reproducibility by employing as carrier gas of hydrochloride to be reacted with group III element material one or more types of inert gases or one or more types of mixture gas of inert gas and hydrogen gas. CONSTITUTION:Inert gas like nitrogen gas is used instead of hydrogen as carrier gas of hydrochloride to be introduced from a second gas inlet tube 3. Main reaction in a Ga containing boat is represented by Ga+HCL GaCl+1/2H2. The lower the hydrogen partial pressure in an atmosphere is, the greater the reaction is advanced rightside, i.e., in a direction for reducing unreacted hydrochloride. Accordingly, when inert gas is used as the carrier gas of hydrogen chloride gas, the reaction of Ga with the hydrochloride can be conducted in a state that hydrogen partial pressure is low, thereby reducing unreacted hydrochloride. Therefore, when the inert gas is used, the unreacted hydrochloride transported to the vicinity of a substrate without reacting with Ga is reduced in a Ga containing boat, and a GaAs layer of high purity is grown on the substrate.

Title: Screen for photogravure
Inventor: EGASHIRA YASUROU
IPC: G03F7/00
Filed: 1982-06-14
Abstract: PURPOSE:To improve the area rate of blackened parts and to reproduce boundary parts between picture parts and nonpicture parts smoothly by making white lines in one direction different in width from white lines in the other direction on a screen for photogravure. CONSTITUTION:The width of segments 8 of a segment pattern in one direction is made narrower than that of segments 7 in the other direction on the screen for photogravure. When a photogravure printing plate is made by using the screen, parts corresponding to thick white lines 7 of the screen for photogravure are banks 9 and parts corresponding to thin white lines 8 are left as projecting parts 10 only at intersection parts of the banks 9 while the other parts are eliminated by side etching. Therefore, when screen lines nearly as many as usual are secured, the area rate of blackened parts is increased and when the area rate of blackened parts nearly as great as usual is secured, the number of screen lines is increased. Further, boundary parts between picture parts and nonpicture parts are reproduced smoothly.
