Title: Multi-volume audit trace for fault tolerant computer
Inventor: MAIKERU JIEI SUKAAPEROSU
IPC: G06F12/00
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To utilize a stored audit trace file for restoring on-line by enabling an audit trail constitution control processor to control the generation, renaming and erasing of the audit trace file on an audit trace disk storage device. SOLUTION: Both of a data disk processor 200 and the audit trace constitution control processor 220 generate an audit record so as to allow restoration to a consistent state in case of a fault. Primary and backup ADP controls the access of a disk volume storing the audit trace file. Primary ADP is normally provided with the control of disk access but in case of a fault, it is replaced with backup. In order to allow this taking over, primary ADP sends a periodical check point to the backup including all disk state information necessary for smooth taking over. These processings mutually work by exchanging messages through a messaging system 222.

Abstract: PURPOSE:To obtain the transistor of small area by forming an element region and a channel cut region in self-alignment manner by a method wherein the exposed surface of an island serving as the element region is etched after removal of the first Si oxide film, and the surface after the etching is covered with an Si oxide film. CONSTITUTION:An N type epitaxial layer 130 is formed on a semiconductor substrate 110, and an Si oxide film 140 and an Si nitride film 150 are formed by superposition. These films are selectively etched so that the element region 100 may remain, and the layer 130 is converted into an Si oxide film 160 about by the half thickness by selective oxidation, and is then removed. When an Si nitride film 170 and a polycrystalline Si film 180 are formed by superposition and then doped with boron, a region 200 is selectively etched because of no doping under eaves 190 at this time. A groove is formed by etching the epitaxial layer 130 exposed by removal of the nitride film 170. Then, the channel cut region 230 is formed by boron doping. The epitaxial layer at the element isolation region is all converted into an Si oxide film 240 by selective oxidation.

IPC: H01L21/304
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To enable effectively flatening the surface of a work wherein step- differences are generated on the surface, with a small working amount and a short working time, by polishing the surface while electric field is generated between the abrasive cloth and the work to electrically attract abrasive grains to the abrasive cloth side. SOLUTION: The surface of a silicon wafer (work) 1 having protrusion patterns 1d on the surface is polished by supplying colloidal silica 8 in the sate of suspension to a gap between the surface and an abrasive cloth 5 which is relatively moved coming into contact with the wafer 1 and composed of polyurethane form. The colloidal silica 8 is charged to negative polarity in suspension 7 whose PH is adjusted, stably separated and levitated. Since the colloidal silica 8 is forcibly attracted to the abrasive cloth 5 with electrostatic force by a voltage applying means 22, the colloidal silica 8 does not act on the bottom of a recessed part 1e on the surface of the wafer 1, and protruding parts 1d are selectively worked. Thereby the surface of the wafer 1 on which step-differences are generated can be flatened with small working amount and short working time.
