Accordingly, current may be increased with a reduction in drain-source on resistance, and an area of the isolation layer can be reduced, as compared to an existing isolation layer, potentially resulting in a reduction in chip area.Type: GrantFiled: March 4, 2003Date of Patent: August 10, 2004Assignee: Samsung Electronics, Co., Ltd.Inventors: Hwa-Sook Shin, Soo-Cheol Lee

Publication number: 20020153578Abstract: Wafer buffering systems for use with a wafer processing system include a frame and wheel. The wheel includes a plurality of shelves for supporting a plurality of wafer carriers. The wheel is supported by the frame for rotation about a generally horizontal axis. The plane of the wheel faces a semiconductor processing system (e.g., a cluster tool) with an intervening wafer transfer robot located preferably between the wheel and the semiconductor processing system. A cassette transfer system moves cassettes from the wheel to a port for interfacing with the wafer transfer robot. In another arrangement, a horizontal carousel stocks cassettes above the processing system.Type: ApplicationFiled: February 28, 2002Publication date: October 24, 2002Inventors: Ravinder Aggarwal, Ivo Raaijmakers

Publication number: 20020125539Abstract: An isolation region is embedded in a semiconductor substrate. The height of the upper face of the isolation region is substantially equal to the height of the surface of the semiconductor substrate. A gate electrode is formed on a gate insulating film and over the isolation region. A first side face of the gate electrode is formed over the isolation region. A second side face of the gate electrode is formed over the active region. A field insulator is formed on the isolation region. A first side face of the field insulator contacts with the first side face of the gate electrode.

Patent number: 6365945Abstract: A submicron semiconductor device having a self-aligned channel stop implant region, and a method for fabricating the semiconductor device using a trim and etch is disclosed. The semiconductor device includes a plurality of active regions separated by insulating regions. The method for fabricating the device includes depositing a nitride over a substrate and selectively covering the active regions with a mask, wherein the mask extends beyond boundaries of the active regions to narrow the width of the insulating regions. Thereafter, a channel stop implant is performed to form channel stops. The mask is then trimmed to the boundaries of the active regions after formation of the channel stops, followed by etching the nitride in exposed areas of the mask. Field oxide is then grown in the insulating regions, whereby the field oxide is self-aligned to the channel stops.Type: GrantFiled: May 2, 2000Date of Patent: April 2, 2002Assignee: Advance Micro Devices, Inc.Inventors: Michael K.
