Title: Formation of gate insulation film
Inventor: YOSHIDA MASAYUKI
IPC: H01L21/28
Filed: 1982-04-28
Abstract: PURPOSE:To obtain a gate insulation film having radiation resistance and high reliability, by performing treatment of two stage system over different specific temperatures. CONSTITUTION:An SOS substrate is treated in O2 at 925 deg.C or more for 30min, and accordingly an SiO2 thin film of good film quality is formed. The amount of change of threshold voltages due to the irradiation of gamma rays is small at less than 925 deg.C, but gate breakdowns increase. Next, further, an SiO2 film is formed under the SiO2 film by performing an H2 combustion oxidation at 900 deg.C or less for approx. 20min. It is preferable that the second SiO2 film has thickness of 100Angstrom  or more from an Si-SiO2 interface. By this constitution, a gate oxide film with less gate breakdowns and reinforced radiation resistance can be obtained, and the device is completed by providing source, drain, and gate regions, and electrodes as normal thereafter.

Abstract: PURPOSE:To improve reliability and moisture resistance simultaneously by positioning the upper surface of a semiconductor chip and the upper surface of an inner lead in the same plane and positioning the center in the thickness direction of the semiconductor chip and the center of height of a package at approximately the same position. CONSTITUTION:The center of a chip 1 and the center of a package 2 are conformed (R1=R2) with each other, and the upper surfaces of inner leads 3 and the height of the surface of the chip 1 are made coincide.
