Patent JP-S62291177-A (JP)
Title: Semiconductor device
Inventor: KOIKE RYOICHI
IPC: H01L29/78
Filed: 1986-06-11
Abstract: PURPOSE:To reduce the diffusing capacity of a semiconductor device by forming an insulating film on the bottom of a groove formed on a semiconductor substrate of source and drain regions of an MOS semiconductor device, and further forming a metal or semiconductor on the film, thereby avoiding the erasure of the charge stored due to an alpha-ray. CONSTITUTION:An insulating layer 17 is formed in the bottoms of source and drain regions 15, 13 of an MOS transistor, and most of the contact of the source and drain regions with a substrate 19 is separated to the substrate 19 and the layer 17. Thus, since the bottom of the source 15 and the drain 13 are separated by an SiO2 film from the substrate, charge stored in the source and drain due to an alpha-ray is not erased in the bottom by recombination, the influence of the alpha-ray is veceived only at the sidewall, thereby reducing the influence significantly as a whole. The SiO2 film 17 of the bottom of the source and drain 15, 13 is increased in thickness (3000Angstrom  or larger) to reduce the parasitic capacity of the source and drain 15, 13.

Abstract: PURPOSE:To carry out measurement at high accuracy for a portion of small curvature radius and for which high density arrangement of thermocouple is needed by molding the portion of small curvature radius on the surface of a model out of a heat bad conductor, and by installing the thermocouple on a thin metal piece. CONSTITUTION:A main wing front end part of small surface curvature radius of a model main body 1 made of metallic material is molded out of a heat bad conductor 2, while holes 3 penetrating from the surface to the rear surface are formed on a plurality of aerodynamic heating factor measurement points there. A thin metallic piece on which a measurement point of a thermocouple 4 is installed is buried in the hole so that the surface will be of the same level as the surface of the heat bad conductor 2. Measurement time is expedited as fast as possible by using the thin metallic piece 5, and by enclosing the surroundings with the heat bad conductor 2, heat conduction to the surroundings is suppressed to a lowest possible level, which leads to minimization of measurement error of the aerodynamic heating factor. Measurement of high accuracy at a point of small curvature radius of model surface, and for which high density arrangement of thermocouple is needed, is thus made possible.
