Title: Semiconductor device and its manufacture
Inventor: MATSUOKA FUMITOMO
IPC: H01L21/336
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To avoid resistance increase of a silicide layer by selectively etching a gate electrode and a burial element separation insulation film that is not covered with a side wall insulation film and lowering it from the surface of an Si substrate. SOLUTION: A side wall insulation film 307 for covering the side wall of a gate electrode 305 is formed. Then, the gate electrode 305 and a region 303 of a burial insulation film that is not covered with a side wall are partially etched in the thickness direction, thus lowering the surface of the burial insulation film 303 as compared with the surface of an Si substrate 301 excluding a part that is covered with the gate electrode 305 and a side wall insulation film 307. Therefore, in the structure of a semiconductor device where the buried element separation insulation film and silicide structure are combined, the peripheral end of a diffusion layer does not touch the buried element separation material when changing an Si surface at a fine diffusion layer region in question into silicide, thus preventing the resistance of the silicide layer from increasing.

Filed: 1994-12-26
Abstract: PURPOSE: To provide an optical modulation element excellent in contrast property by making the difference of reflectance between a protective layer and a polymer matrix to a specific value or below so as to prevent the decrease in contrast. CONSTITUTION: The protective layer having smooth layer surface is formed on the surface of a liquid crystal/polymer composite film formed on a substrate and the difference between the reflectance of a polymer material forming the protective layer and that of a polymer material forming the matrix of the composite film is controlled to <=0.05.

Inventor: TOKUNAGA KENJI
IPC: B65D85/86
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To eliminate deposition of contaminant to an object to be processed such as semiconductor wafer, etc., and reduce the consumption energy. SOLUTION: This carrier cassette is provided with a box-type cassette body 2a, which is provided with a square opening 2c to stack up a plurality of semiconductor wafers in its space for storage and to carry in/carry out the semiconductor wafer, and a door part 2b which covers the opening 2c and tightly closes the cassette body 2a.

Patent JP-H07193976-A (JP)
Title: Power interruption system
Inventor: TANAKA TAKASHI
IPC: H02H3/00
Filed: 1993-12-28
Abstract: PURPOSE:To ensure safety when an adapter interrupted by overcurrent is reset automatically. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted by an overcurrent and a receptacle. When the detected current exceeds a contract current limit, the breaker 1 interrupts the adapters sequentially and if the detected current exceeds the limit even after interruption of all adapters, the breaker interrupts. The breaker resets the adapter upon elapse of a predetermined time, and if the current level increases due to reset, the adapter is interrupted again. The appliances are interrupted only partially even if the current exceeds the limit and when the current exceeds it continuously, the breaker functions to interrupt power in safety. Since an appliance for which the switch is not turned OFF is not reset, the adapter can be reset easily in safety.

Title: Semiconductor laser module
Inventor: NAKANISHI HIROMI
IPC: H01S5/022
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to attach and detach an optical fiber having parallel end faces without using a dummy fiber by setting the length of the optical path between the end face on the semiconductor laser chip side and the optical incidence end face of a light sensitive body within a specified range. SOLUTION: Letting the optical resonator length of a semiconductor laser chip (chip) be Lc, the length of the optical path between the end face of the chip on the projection side and the optical incidence end face of a light sensitive body be La and N be an integer, the optical path length is set so that the following equation will hold: NLc<La<= N+(1/6)}Lc or  N+(5/6)}Lc<=La<(N +1)Lc. Even if reflected light 20 returns to the semiconductor laser, therefore, fluctuation in the output of the semiconductor laser due to variation in temperature is reduced because the phase of the reflected return light does not agree with the phase of light determined by an internal resonator. Fluctuation in differential quantum efficiency is also within a desired range.  In other words, the operation of the semiconductor laser is not made unstable by return light 20 even if a flat optical fiber 8 is opposed to the semiconductor laser.
