Title: Improved method of making oxidizing zone of area silicon oxidation method grow
Inventor: CHIYOU TENSEI
IPC: H01L21/316
Filed: 1993-12-27
Abstract: PURPOSE: To reduce the length of a bird's peak and to increase a utilization area by forming a one-layer nitrogen atom on an interface between a wafer and an oxide layer by the oxide layer that is grown by nitrous oxide and reducing an oxidation speed. CONSTITUTION: A silicon wafer is fed into a high-temperature oven and an oxide layer 22 is formed on a silicon substrate 20 through nitrous oxide gas. The silicon wafer is fed to a low-pressure chemical gaseous phase deposition system of silicon nitrogen and a silicon nitrogen film 23 is laminated on the oxide layer 22. After a zone required for LOCOS is developed by a host mask, it is oxidized by wet oxygen, thus forming a zonal silicon oxide film 24. A layer of N atoms is deposited on an interface 21 of SiO2 and Si due to the reaction, and the N atoms prevent the diffusion of oxygen atoms, thus reducing an oxidation speed and reducing the length of a bird's peak.

Title: Cpu monitoring device
Inventor: INAMORI CHIEMI
IPC: G06F11/30
Filed: 1988-12-28
Abstract: PURPOSE:To easily investigate the cause of abnormality occurrence by proceeding to interruption processing if abnormality occurs to a CPU and storing processing data at the time of the abnormality occurrence. CONSTITUTION:An oscillator 1 outputs a pulse signal periodically and a counter circuit 2 counts the supplied pulse signal. The CPU 3, on the other hand, outputs a counter control signal which clears the counted value of the counter circuit 2 at a proper period which is longer than the period of the pulse signal. If operation abnormality occurs to a module of application, the CPU 3 does not supply the counter control signal for initialization to the counter circuit 2 any more and an interruption signal is supplied to the CPU 3 when the counted value of the counter circuit 2 reaches a prescribed counted number, thereby proceeding to the interruption processing. In this interruption processing, register contents, periphery information on the CPU 3, etc., at the time of the abnormality occurrence are stored in a memory. Consequently, the cause of the abnormality occurrence is easily investigated.
