Title: Manufacture of semiconductor device
Inventor: HIGUCHI TOSHIHIKO
IPC: H01L21/3205
Filed: 1991-10-16
Abstract: PURPOSE:To prevent a high melting point metal from remaining in an insulating film mainly comprising a silicon oxide thus avoiding the deterioration in characteristics and the failure of a semiconductor device by subjecting an element isolation insulating film to an etching treatment after selecting etching the high melting point metal and a metallic silicide. CONSTITUTION:Silicon contained in a high melting point metal 17, a semiconductor substrate 1 or a wiring 3 is reacted with one another in an inert gas atmosphere so as to form a high melting point metallic silicide 8. Next, the high melting point metal 7 excluding the silicide 8 on the surface of the semiconductor substrate 1 is removed by selective etching step. Later, the surface of an element isolation insulating film 2 and a sidewall spacer insulating film 5 mainly comprising a silicon oxide is etched way so as to simultaneously remove an infinitesimal high melting point metallic silicide 10 formed on the surface part. Through these procedures, the rate of failure of semiconductor formed during the metallic silicide formation step can be decreased thereby enabling the reliability upon the semiconductor device to be enhanced.

Abstract: PURPOSE: To make measuring equipment lightweight by installing an enclosure in the surrounding of a reflecting mirror to which a temperature sensor is attached, introducing nitrogen gas into the enclosure, installing a heat insulating vacuum layer on the side of the reflecting mirror, installing a Stirling cycle refrigerator adjacent to the reflecting mirror, and detecting frost generating on the mirror. CONSTITUTION: A temperature sensor 2 is installed in the position coming in contact with a reflecting mirror 1 or in the nearest position to the reflecting mirror 1, an enclosure 3 is installed in the surrounding of the mirror 1, and nitrogen gas is introduced into the enclosure 3 through an inlet 4 and an outlet 5. A zirconia base getter material is placed in a heat insulating vacuum layer 6 on the side to absorb gas on the inside. A Stirling cycle refrigerator 8 controls temperature with an inverter. During measurement, gas under measuring is introduced to the position of the reflecting mirror 1 from the inlet 4. The trace moisture in the gas forms frost on the reflecting mirror 1. Thereby, light from a laser beam irradiating device 10 is reflected or scattered, and variation of reflected or scattered light is read out with a light receiving device 11 to judge a frost point.  Temperature at this point is measured with the sensor 2. By using the refrigerator 8, equipment is made compact and lightweight.

Title: Method and device for depositing sound film
Inventor: KOGURE NAOAKI
IPC: H01L21/285
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for depositing a sound film by which generation of undesirable internal stress in the film after deposition can be previously prevented. SOLUTION: A plating film is deposited to a prescribed thickness on a substrate surface by using a film-forming soln. (a plating soln.) 25a in a state where elastic deformation of prescribed displacement quantity is previously imparted to a base material such as a semiconductor wafer 100. After film-forming is completed, the elastic deformation of the base material is released to recover a shape in an undeformed state before deformation. Namely, since the base material is previously imposed with the deformation which generates stress reverse to the internal stress generating in the base material by film-forming and the film is formed on the surface in this state, most or a part of the internal stress generated in the deposited film is countervailed by releasing the deformation after film-forming and thereby the sound film is obtained.
