Title: Diffusion mask for use in manufacture of semiconductor
Inventor: KOYA KENICHI
IPC: H01L21/22
Filed: 1988-10-25
Abstract: PURPOSE:To suppress diffusion in the interface direction and enable refinement of a semiconductor device by using one or more diffusion mask layers on a compound semiconductor and turning the main element of one layer on the compound semiconductor side to be silicon. CONSTITUTION:A silicon film 5 is provided as a first layer of a diffusion mask, and a silicon oxide film 6 is further provided on the silicon film 5 to form a two-layer diffusion mask. The silicon film scarcely produces a modified layer formed of oxide or the like at the interface of the compound semiconductor during the formation of the silicon film and forms a more dense film, and further the values of the thermal expansion coefficient and the lattice constant of the silicon film 5 are approximate to those of the compound semiconductor such as GaAs, InP, so that the thermal damage during the temperature rise or fall can be reduced. Thus, the diffusion in the direction along the interface between the compound semiconductor and the diffusion mask can be suppressed and the refinement of the semiconductor device is enabled.

Abstract: PROBLEM TO BE SOLVED: To stabilize combustion gas for premixing combustion over a wide operation range by adding vapor in a vapor system to fuel, which is fed from a fuel supply system of a fuel tank, providing a fuel reformer generating reformed fuel, and feeding the reformed fuel generated from the fuel reformer to a gas turbine combustor. SOLUTION: In a starting operation, fuel fed from a fuel tank 26 to a fuel reformer 29 is divided into two flows to a burner 30 and to a reforming catalyst 31. The burner 30 is operated so as to generate combustion gas from the fuel fed from the fuel tank 26, and if reformed fuel is generated from the reforming catalyst 31, a part of the reformed fuel is fed for combustion via a bypass system 32. The fuel reformer 29 increases a combustion gas temperature in the burner 30, and when the reforming catalyst 31 starts generating reformed fuel, the reformed fuel is fed to a burner 30 using the bypass system 32, so that NOx concentration of exhaust gas discharged from an exhaust duct 34 is suppressed low. Then, the reformed fuel is fed to a gas turbine combustor 19 as fuel for turbine driving combustion gas.

Abstract: PROBLEM TO BE SOLVED: To conduct the cooling design of a motor body and a control unit individually, so as to use the motor body also as a constant speed motor by forming opposite surfaces of a case storing the control unit and the motor out of a material whose thermal conduction is low. SOLUTION: A portion between a motor body 10 and a case-fitting part 22 for control unit 20 case receives the radiant heat of the motor body 10, even if an aerial layer 30 is formed. Therefore, the material of the case-fitting part 22a is formed out of a material whose heat resistance is high, such as an insulation member to reduce the thermal effect further, by which it is possible to reduce thermal effect upon the inside of the control unit 20 further. By applying metallic processing with metal, such as aluminum or zinc to an opposing surface of the case-fitting part 22 to the motor body for finishing it to a glossy surface, the reflectance of radiant heat becomes higher, so that the control unit 20 can further reduce the thermal effect from the motor body 10.
