Title: Pattern forming method
Inventor: YAMASHITA HIROSHI
IPC: H01L21/3065
Filed: 1983-02-09
Abstract: PURPOSE:To enable to form the thin film pattern with rectangular cross section by a method wherein an aperture pattern having the prescribed cross section is formed on the resist film located on a substrate, and after a thin film has been formed on the whole surface, an etching is performed on the thin film until the uppermost part of the resist film is exposed and said resist film is removed. CONSTITUTION:A resist material layer 2 of 1mum in thickness is rotary-painted on a silicon substrate 1, and a pattern is formed after exposure and development processes have been performed. Then, an organic silicon compound film of 1mum in thickness is formed by rotary-painting an organic solution containing silicon compound, said silicon compound film is dried up and sintered, and a silicon oxide film 3 is formed. The silicon oxide film 3 is removed as deep as to the surface of the resist material layer 2 by performing a dry etching. C3F8, for example, is used for this dry etching with the degree of vacuum of 10<-3>Torr and the RF power of 300W. Then, the microscopic pattern of silicon oxide film 3 is obtained by removing the resist material layer 3 using aceton boil or oxygen ashing.

Title: Semiconductor device
Inventor: OGAWA SUMIO
IPC: H01L27/04
Filed: 1989-01-30
Abstract: PURPOSE:To always detect a substrate potential correctly and to control a feedback without delay by a method wherein a detecting part of a substrate potential detector is installed near a maximum leakage-current source of a potential change in a semiconductor substrate. CONSTITUTION:An FET Q1 used as a maximum leakage-current source is formed in an FET substrate 1. A detecting part (detecting terminal) of an SD 2 is installed near the FET Q1. The SD 2 detects a substrate potential VSD near the FET Q1, outputs a feedback signal FB to a substrate-potential generation circuit (BBG) 3 and adjusts a potential-output capacity of the BBG 3. The BBG 3 supplies a substrate potential VBB to the FET substrate 1 on the basis of the feedback signal PB. The FET Q1 generates a substrate leakage current by means of a switching operation and changes the substrate potential near the FET Q1; however, since the SD 2 has detected the potential near the FET Q1 in advance, it can quickly change a capacity of the BBG 3, and the substrate potential is stabilized.

Abstract: PURPOSE: To stably receive a digital modulated signal such as a multi-level QAM by removing interference from an analog modulated signal by providing a low-pass filter means for attenuating signals of a differential frequency from the respective carrier frequencies of analog modulated signals adjacent to the synchronizing detected digital modulated signal.

Thus the signals A of the live picture are successively inputted to the circuit 1. The picture signals C which are successively obtained in such a manner are subtracted with the signals B read successively out of an picture memory 3 via a subtraction circuit 4. The background pictures of both pictures obtained at the subtracting side and the subtracted side are defined as pictures BZ. Thus it is possible to obtain in real time a subtraction picture of only blood vessel which is free from any motion artifact.
