Title: High-emissivity far infrared emitter and its production
Inventor: ISHII KAZUHIDE
IPC: F24C15/24
Filed: 1988-07-26
Abstract: PURPOSE:To improve emissivity by specifying the composition of a steel and also forming an oxide film into a shape of projections having a length of a specific value or above in an emitter made of stainless steel on which an oxide film is formed by means of high-temp. oxidation. CONSTITUTION:After blasting treatment is applied to the surface of an Fe-Cr-Si stainless steel containing, by weight, 10-35% Cr, 1.0-4.0% Si, and <=3.0% Mn, this steel is held in an oxidizing atmosphere at 900-1200 deg.C for >=15min, by which an oxide film in a projected state having >=5mu length is formed on the steel surface. When Si content in the above steel is less than 1.0%, the oxide in a projected state cannot be formed, and, when it exceeds 4.0%, the steel becomes brittle. In order to form the oxide in the projected state of >=5mu length on the surface, it is preferable to previously apply high-degree working strain to the steel-sheet surface prior to high-temp. oxidation treatment, and, as a means therefor, blasting treatment is applied to the surface. Further, when high-temp. oxidation treatment temp. is below 900 deg.C, the oxide film in projected state cannot be formed, and, when it exceeds 1200 deg.C, the deformation of the stock is increased.

Title: Method of forming insulating film in semiconductor device
Inventor: MORITA TATSUO
IPC: H01L21/31
Filed: 1981-11-17
Abstract: PURPOSE:To reduce a thermal influence upon semiconductor elements by a method wherein after providing an insulating film deposited in the form of a layer, a laser beam is irradiated to make heat treatment with short-time heating. CONSTITUTION:A laser beam 22 emitted from a laser oscillation tube 21 passes a window 25 of a container via a mirror 23 and a lens 24, and then it is irradiated onto a protective insulating film 12 on a semiconductor device placed in the container. Atmospheric gas is introduced into the container via an inlet port 27 and discharged therefrom via an outlet port 28. Upon irradiation of the laser beam, the protective insulating film 12 is given with thermal energy and heated up to 800 deg.C or thereabout in a short time for heat treatment, so that a filling density of the film is enhanced and minute voids or cracks are eliminated. Because this heat treatment is made by short-time direct heating, only the protective insulating film 12 is heated and other portions are prevented from suffering an adverse influence due to heating. Thus, a characteristic of the semiconductor device is not deteriorated.
