Filed: 1988-09-20
Abstract: PURPOSE:To stably form an oxide film having desired film characteristics with superior reproducibility by generating glow discharge between an oxide target and a substrate and determining a sputtering pressure at the time of film formation based on the emission spectrum intensity of oxygen atoms. CONSTITUTION:A sputter gas, such as Ar, is introduced from a cylinder 7 into a chamber 1, and the pressure in the chamber 1 is regulated to the prescribed value by means of an exhaust system 11. An oxide target 3 of SiO2, etc., and substrates 5 are disposed in the above chamber 1 in a manner to be opposed to each other, and a high-frequency voltage is impressed from an electric power source 6 via holders 2, 4 to generate glow discharge, by which the target 3 is sputtered and films of oxide, such as SiO2, are formed on the substrates 5, respectively. At this time, at the time of film formation or before film formation, the flow rate of the sputter gas is held constant and gas pressure in the chamber 1 is changed to monitor the emission spectrum in glow discharge. Just before the emission intensity of oxygen atoms in the above rises suddenly, the sputtering pressure is fixed for the sputtering pressure at the time of film formation. By this method, film-forming conditions for stably forming the oxide film having the desired characteristics with superior reproducibility can be determined in a short time.

Title: Semiconductor device and manufacture thereof
Inventor: NIIYAMA YUJI
IPC: H01L29/78
Filed: 1990-09-05
Abstract: PURPOSE:To suppress operation of parasitic transistors without eroding element formation regions by specifying the width and depth of channel cutting one- conductivity-type layers. CONSTITUTION:Channel cutting p<+> diffusion layers 12 formed under element isolation regions A are narrower than element isolation SiO2 films 5, therefore, they do not reach element formation regions B. Because the p<+> diffusion layers 12 are much deeper than n<+> diffusion layers 13, channels formed under gate electrodes 9 through the element isolation SiO2 films 5 are cut by the p<+> diffusion layers 12 and carriers do not move between the n<+> diffusion layers 13 across the element isolation regions A. Thereby the channel cutting p<+> diffusion layers do not erode the element formation regions and operation of parasitic transistors formed across the element isolation regions is suppressed.
