IPC: H01L21/316
Filed: 1987-10-30
Abstract: PURPOSE:To provide a tunnel oxide film with excellent endurance characteristics by a method wherein the tunnel oxide film is constituted in a three layer structure to form nitroxide layers respectively on both surfaces of a silicon oxide film. CONSTITUTION:A chamber vacuumized, after leading-in a reaction gas, is heated up to high temperature to remove a natural oxide film and, after pressure reduction for exhaust, O2 is led in the chamber. The semiconductor wafers in this chamber are heater up to high temperature to form a silicon oxide film. Next, a nitrifying reaction gas NH3 led in is rapidly heated by a rapid heating means to be nitrified rapidly. Furthermore, nitrogen is led in the chamber to take out the semiconductor wafers. A tunnel oxide film in a three layer structure to form a nitroxide film on both surfaces of the silicon oxide film thus formed can be constituted by rapidly heating the silicon oxide film by a halogen lamp in NH3 gas atmosphere.

Title: Automatic control method of control parameter
Inventor: INOUE AKIRA
IPC: G05B13/00
Filed: 1984-12-28
Abstract: PURPOSE:To improve the control accuracy as well as the product quality by controlling automatically the IP control constant by a simple algorithm to the characteristic variance of a control subject which is approximated by a primary delay system and securing a desired control response at all times. CONSTITUTION:A controlled system identifying part 12 calculates the gain K and the time constant T at a certain time point for each control synchronization. An IP control time constant control part 13 calculates the proportion gain KP and the integration time TI of an IP controller by an algorithm so that the attenuation coefficient and the excessive time tp set to the gain K and time constant T are fixed. Then the IP control constant of a DO control part 10 is changed for calculation of the target ventilation amount (ur). Thus the time tp is fixed despite the characteristic change of the controlled system. This satisfies the responsiveness. In addition, the tp and the attenuation coefficient zeta is fixed together with the stability secured. Thus the desirable control response is always secured.
