Title: Manufacture of thin film semiconductor device
Inventor: TAKENAKA SATOSHI
IPC: H01L21/324
Filed: 1990-10-17
Abstract: PURPOSE:To enable an Si film in large crystal particle diameter of several mum to be formed further enabling a clean Si/SiO2 interface to be formed by a method wherein a non-single crystal semiconductor thin film is solid-grown on an insulating amorphous material in the oxygen atmosphere at the specified oxygen gas partial pressure. CONSTITUTION:An insular amorphous silicon thin film 1-3 is solid-grown. The annealing atmosphere mainly comprising oxygen gas at the partial pressure exceeding 99.99% is applicable. That is, any mixed impurities are so little that the clean annealing step may be assured. The solid annealing temperature is specified to be at 500 deg.C-700 deg.C while at the low temperature, the crystal particles only in the crystal direction displaying feeble activating energy to the crystal growth are selectively and slowly grown larger. Furthermore, a very thin oxide film 1-5 is formed on the silicon surface simultaneously with the solid growth due to the heat treatment in the oxygen atmosphere. At this time, the thin oxide film 1-5 can be formed even at such a low temperature of 600 deg.C since the oxidation rate is accelerated in the initial oxidation phase. During the heat treatment process extending over 16 hours, the silicon crystal particle diameter exceeds 2mum while the thin oxide film 1-5 becomes about scores of Angstrom  thick.

Title: Recording paper leading end detection mechanism
Inventor: KOBAYASHI TAKAO
IPC: B41J13/00
Filed: 1990-10-17
Abstract: PURPOSE:To eliminate a misregistration of recording colors to obtain a high- quality recording by a method wherein a recording paper leading end detection means is so disposed as to detect a recording paper leading end at a low curvature part of a detection directional curve. CONSTITUTION:A recording paper leading end detection means 26 made of a light reflecting detector is characterized by a detection directional curve 26a representing a position where the leading end of recording paper 2 is detected at a set detection level. The recording paper leading end detection means 26 mounted on a mounting board 30 is inclined at an angle of theta degrees and spaced a center detection distance X2 so that the leading end of the recording paper 2 can be detected at a low curvature part of the detection directional curve 26a. The feed position of recording paper 2 is freely shifted from P1 to P3 through P2 within a section X1. Since the recording paper leading end detection means 26 detects the leading end of the recording paper along the detection directional curve 26a to cope with this change, a detection error Y1 in a recording paper feed direction is generated. However, the value of the detection error Y1 can be remarkably reduced. In this manner, a misregistration of recording colors is reduced.
