Title: Method for etching semiconductor layer and manufacture of semiconductor light emitting element using the same
Inventor: YANO HITOHISA
IPC: H01S5/323
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To etch a thick semiconductor layer by using a thin etching mask by using an easily-oxidizable metallic film for an etching film and performing the etching while an oxidizing source is supplied for oxidizing the metallic film. SOLUTION: After a Ti film 3 and a photoresist film 4 are successively formed on the surface of a semiconductor layer 2, the part corresponding to the prescribed etching area of the semiconductor layer 2 is opened by patterning (a). Then the prescribed etching part of the semiconductor layer 2 is exposed by etching the Ti film 3 by using the photoresist film 4 as a mask (b). Thereafter, the semiconductor layer 2 is etched by the CAIBE method by using the photoresist film 4 and Ti film 3 as masks while an oxygen gas is supplied. When the oxygen gas is supplied, the exposed surface of the Ti film 3 is oxidized to TiO2 by the oxygen and the Ti film 3 becomes to be hardly etched. Therefore, precise perpendicular etching can be performed easily by improving the patterning accuracy, because the etching mask can be formed in a very thin film.

Title: Video tape recorder
Inventor: KUDO JUNICHI
IPC: H04N5/92
Filed: 1985-06-10
Abstract: PURPOSE:To reproduce a distinct image without damaging a tape even at the time of running of fast-feeding and rewinding, by providing an azimuth head having an inclination against a control head. CONSTITUTION:A modulated signal passes through a recording amplifier 35 containing an amplifier circuit, and it is recorded onto a tape by an azimuth head 36 whose azimuth angle is different from a control head. When executing a reproduction, a video signal does not appear in the control head due to an azimuth effect, and only a control pulse appears. On the other hand, the control pulse and the video signal are superposed to the azimuth head 36. As for a reproducing signal which has passed through a reproducing amplifier 37, the control pulse is separated, and only the video signal exists. The reproduced video signal is separated into a video signal data and a clock by a demodulation circuit 38. The separated signal data is a serial data, therefore, converted to its original signal data by an S/P conversion circuit 39, and returned to a memory 32. The signal which has been stored temporarily in the memory is returned to its original analog video signal by a D/A converter 40.
