Title: Manufacture of semiconductor device
Inventor: SATO YOSHIO
IPC: H01L29/792
Filed: 1985-02-08
Abstract: PURPOSE:To obtain an EEPROM having high reliability by forming a gate oxide film partially having a thin-film section onto a semiconductor substrate and shaping a diffusion layer under the thin-film section. CONSTITUTION:An SiO2 film in thickness of approximately 500Angstrom is formed into a region, in which the surface of a P-type Si substrate 21 is partitioned by a field insulating film 22, through oxidation treatment. An opening 24 is bored to one part, and an SiO2 film 25 in thickness of approximately 100Angstrom  is shaped onto the exposed substrate 21 through second oxidation treatment. When the ions of an N-type impurity are implanted while selecting acceleration voltage at approximately 30keV, an N layer 27 is acquired only under the thin-film 25. According to the constitution, the Si substrate is oxidized directly and the gate oxide thin-film 25 is formed, thus improving the control of the thickness of the thin-film. When an EEPROM is manufactured by utilizing a thin-film section 6 and an N layer 5 under the thin-film section through the same process as a conventional method, thus obtaining a cell having high reliability.

Title: Photosensitive device
Inventor: TAKEUCHI MASARU
IPC: H01L27/14
Filed: 1983-02-14
Abstract: PURPOSE:To inhibit the scattering of incident light and the deterioration of S/N by covering the surface of light incidence of an optical filter with a photo transmitting photo receiving substrate. CONSTITUTION:The photo receiving substrate 10 is composed of a photo transmitting material such as glass and plastic and is adhered to the surface of light incidence of the optical filter 6 via a photo transmitting adhesive 11, thus covering the exposed surface of light incidence of the filter 6 so as to shield it from the outer air. Thereby, the damage of the filter 6 is prevented; even if the substrate 10 is damaged, it does not affect the filter 6, resulting in only the generation of light scattering of negligible degree. Therefore, the light transmitting through the filter 6 is not dissipated, and then the deterioration of S/N can be inhibited.

Title: Operation of adhesive applying device
Inventor: YOSHIDA SATORU
IPC: B05C5/00
Filed: 1989-02-01
Abstract: PURPOSE:To improve the productivity by placing a substrate only on the position corresponding to a normal nozzle on a substrate holding means by controlling a substrate carrying means. CONSTITUTION:A conveyor 1 carries a substrate 2c carried from the upstream side to a position at which the substrate is abutted on a stopper 3. An X-Y table 4 moves substrates 2a and 2b with a pair of parallel holding guides 5. An arm 6 transfers the substrate 2c on the conveyor 1 on a carrying-out conveyor 7. Nozzles 8a and 8b deliver an adhesive from cylinders 10a and 10b by actuating valves 9a and 9b. When a trouble occurs at part of the nozzles due to linkage operations of each functional element, the carrying means is controlled so that no substrate can be placed at the position corresponding to the defective nozzle on a substrate holding means and, at the same time, the valves are controlled so that the delivering operation of the detective nozzle can be stopped. When such constitution is used, the processing capacity drops until the trouble is recovered, but, since the operation can be continued, productivity can be improved and mixture of a defective substrate into the succeeding process can be eliminated.
