Title: Silicon wafer and manufacture thereof
Inventor: SUNAKAWA TAKESHI
IPC: H01L21/322
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration of gettering capacity even after the heat treatment by obtaining the structure that a silicon oxide film is thinned or the oxide film is partly vanished due to the progress of thinning of the oxide film. SOLUTION: A silicon wafer is formed with a silicon oxide film 5 having a thickness of 25 to 50Å on one main surface formed with the device of a single crystal silicon substrate 1, and a polycrystal silicon film 2 on the film 5. The thickness of the film 5 is suitably set in a range of 25 to 50Å, and hence even if it is heat treated at a high temperature for a long time like a well diffusion, the structure that a solid epitaxial grown is not only suppressed, but also the film 5 is thinned or the oxide film is the part by the progress of thinning of the oxide film. Accordingly, the gettering capacity of the silicon 2 is maintained. Thus, the low-cost wafer having excellent gettering capacity can be obtained in simplified steps with high yield.

Title: Semiconductor device
Inventor: TAJIMA HISASHI
IPC: H01L21/331
Filed: 1988-09-21
Abstract: PURPOSE:To obtain a semiconductor device wherein current characteristic is improved without decreasing common emitter current amplification factor hFE even if the emitter size of a lateral transistor is increased by a method wherein an emitter region is formed on an epitaxial layer. CONSTITUTION:The title device is provided with the following; a buried layer 2 of opposite conductivity type formed on the surface of a semiconductor substrate 1 of one conductivity type, an epitaxial layer 3 of opposite conductivity type formed on the semiconductor substrate 1, a first region 5b of one conductivity type in the epitaxial layer 3, a second region 6 of opposite conductivity type formed in the epitaxial layer 3, and a third region 5a of one conductivity type formed on the above epitaxial layer 3. Since the emitter region 5a is formed on the epitaxial layer 3, the emitter-base juction surface exists only on the bottom surface of the emitter region 5a. As a result, the common emitter current amplification factor hFE depends upon the diffusion length of holes and the distance between the emitter and the collector, and does not depend upon emitter size except the injection density of holes from the emitter region 5a.
