Patent JP-H11135475-A (JP)
Title: Manufacture of semiconductor device
Inventor: YONEDA HIROYUKI
IPC: H01L21/3065
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To suppress micro-loading effect preventing high speed etching of a fine contact hole, by etching a film to be etched using a resist film as a mask after removing water existing on the surfaces of the film to be etched and the resist film using particular gas plasma. SOLUTION: After a BPSG film is deposited on a silicon substrate, a contact hole is patterned with a photo-resist. Then, water molecules 2 adhered onto a wafer 1 is ejected by sputtering due to irradiation of inert gas plasma 3 and is exhausted with the aid of the plasma. At that time, the resist and the film to be etched are not etched because inert gas is used. Thus, contact etching process is carried out after removing the water, so that the contact hole etching is performed with plasma having very low hydrogen concentration and a state wherein much radical exists in the bottom part of the contact hole can be obtained.

Abstract: PURPOSE:To reduce the load on each frequency divider and efficiently supply power to each frequency divider and reduce the number of elements to increase the operation speed by interposing a buffer circuit having the level shift function between the frequency divider in the preceding stage and that in the succeeding stage. CONSTITUTION:Buffer circuits 14-having the level shift function are interposed between respective stages of frequency dividers 11, 12- constituted by cascading flip flop (FF) circuits in many stages, and level shift diodes for clock interposed between FF circuits constituting frequency dividers 11, 12- are transferred to buffer circuits 14-. Consequently, level shift diodes for clock constituting respective FF circuits are unnnecessary and the load is reduced from 4a+alpha. (alpha is the wiring capacity for connection to the clock terminal of the following stage) to 2a+beta (beta is the capacity of the interstage buffer). Thus, the load is reduced and the operation speed is increased and the reliability is improved.

Patent JP-H08163774-A (JP)
Title: Temperature controller
Inventor: ITO KEIICHI
IPC: H02H5/04
Filed: 1994-11-30
Abstract: PURPOSE: To prevent wash water of a sanitary washing system from showing an abnormal temperature even if there is something wrong with a control system. CONSTITUTION: A voltage VS at a connection between a thermister 21 which detects a temperature and a volume 32a of a volume section 32 and a reference voltage VREF at a connection between resistors 23 and 24 are compared with each other by a comparator 25 and then a temperature detection signal STC is sent out to a microcomputer 35. A resistance value of a resistor 34 is set to such a value that a temperature of the thermister 21 may be higher than the maximum temperature of water which can be set by the volume section 32 and it also may be a temperature which is not dangerous to users (an upper limit temperature). The voltage VS and a voltage VUL at a connection between the resistor 34 and the volume 32b are compared with each other by a comparator 33 and then the comparator 33 sends out a limit detection signal SLC to the microcomputer 35.  When the signal SLC is high level 'H', the microcomputer 35 outputs a high-level 'H' signal HA independent of the signal STC and turns off a power supply of a heating section 31 for preventing heating of the heating section 31.
