Title: Dry etching method
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L21/3065
Filed: 1981-12-12
Abstract: PURPOSE:To perform a preferable etching by dry etching a compound semiconductor with compound gas of H and halogen atom, thereby preventing the surface or the interior of the semiconductor from contaminating with contaminant or gas molecules. CONSTITUTION:H is dissociated by a discharge in H-halogen compound gas. Since the vapor pressure of the H itself is very high, the H is not accumulated on the surface of a specimen, but the atoms themselves become stable H2 due to the bond of the atoms, but do not almost bond with other atoms, and the surface after etching is cleaned but not contaminated by the gas. The III-V group compound semiconductor such as Ga, As or the like, or II-VI group compound semiconductor such as ZnSe is not affected by the influence of compound semiconductor crystal due to IV group element such as C (incompleteness is introduced to the crystal) different from the case of the discharge of C-halogen compound gas, but is etched cleanly and preferably. When the temperature rise is prevented as required or component element gas having high vapor pressure is mixed in the etching atmosphere, the clean etching with good crystallinity and directivity can be performed.

Title: Mode switching device of preliminary winding type camera
Inventor: NISHIZAWA TETSUO
IPC: G03B17/00
Filed: 1983-10-26
Abstract: PURPOSE:To prevent the multiple exposure of a film which is already exposed if the rear cover of a preliminary winding type camera is opened during film loading operation by providing the rear cover and a switch for detecting the loaded state of a cartridge, and controlling a motor. CONSTITUTION:The motor is normally powdered on forward and backward through a relay switch RLS and a mode changeover switch 400 to perform preliminary winding operation and photographing operation over rewinding operation. If the rear cover is opened in the middle of the photographing operation, the rear cover is closed once more as it is; and then a mechanical switching means is not operated because neither the unloading of the film nor the loading of a new film which is expected is performed, so a cartridge switch ST is held on. Consequently, the film is not all rewound into the cartridge after preliminary winding and the exposed film is prevented from being exposed again.
