Filed: 1987-03-26
Abstract: PURPOSE:To avoid increase of degradation and variation of Vt of an SOI type MOS-FET by forming an oxide film in the region of the bottom surface of a semiconductor thin film except an element isolation region. CONSTITUTION:Oxygen ions are implanted into a semiconductor thin film 8 with a resist layer 9 as a mask to form an oxide film 10 in the region of the bottom surface of the semiconductor thin film 8 except an element isolation region. After the resist layer 9 is removed and the semiconductor thin film 8 is annealed in an inlet gas, the semiconductor thin film 8 is polished until the oxide film 10 is exposed to level the substrate surface and isolate the element. As the SiO2 film 10 as this exists, the gate SiO2 film of a 2nd MOS-FET is thicker than the gate SiO2 film of a 1st MOS-FET. With this constitution, degradation and variation of Vt of an SOI type MOS-FET composed of the 2nd MOS-FET can be avoided.

Abstract: PURPOSE: To improve the quality of sintered ore and also, to stabilize the operation of sintering machine, by controlling the temperature of exhaust air of wind box placed at a specified position of DL sintering machine in a fixed limites.  
     CONSTITUTION: Temperature of exhaust air of #27 highest exhaust air temperature wind box of DL sintering machine, is accurately correlated with that of #23 wind box before five minutes placed nearer side of the ignition lamp 4 than the above box. It is known that the quality of sintered ore is most superior when the highest temperature of #27 wind box is in the extent of 360W410°C. Accordingly, exhaust air temperature of #27 wind box after five minutes is made at 360W410°C and the operation is stabilized by setting up the exhaust air temperature at 200± 50°C and controlling the above temperature by measuring the exhaust air temperature. When the exhaust air temperature of #23 wind box is lowered at 150°C, velocity of the pallet 2 is delayed at 0.2m/min. and the velocity is returned to the original velocity when the temperature is returned to 175°C. Conversely, the velocity of the pallet 2 is quickened at 0.2m/min. when the exhaust air temperature is risen at 250°C. Thus, high quality sintered ore is manufactured stably.
