Abstract: When an oxidation treatment for regenerating a gate insulating film 6 is performed after forming gate electrodes 7A of a polymetal structure in which a WNx film and a W film are stacked on a polysilicon film, a wafer 1 is heated and cooled under conditions for reducing a W oxide 27 on the sidewall of each gate electrode 7A. As a result, the amount of the W oxide 27 to be deposited on the surface of the wafer 1 is reduced.

Abstract: When polycrystalline silicon germanium film is used for gate electrodes in a MOS transistor apparatus, there have been problems of reduced reliability in the gate insulating film, due to stress in the silicon germanium grains. Therefore, a polysilicon germanium film is formed, after forming silicon fine particles of particle size 10 nm or less on an oxide film. As a result, it is possible to achieve a high-speed MOS transistor apparatus using an ultra-thin oxide film having a film thickness of 1.5 nm or less, wherein the Ge concentration of the polycrystalline silicon germanium at its interface with the oxide film is uniform, thereby reducing the stress in the film, and improving the reliability of the gate electrode.

Abstract: A substrate processing apparatus includes a chamber, a gas introducing portion, a gas discharge port, a substrate transfer gate, and a substrate moving member which moves the substrate between a substrate processing position where the substrate is processed in the chamber and a substrate transferring in-out position in the chamber where the substrate transferred into the chamber from the substrate transfer gate is located and where the substrate is located when the substrate is transferred out from the chamber through the substrate transfer gate. The gas introducing portion, the substrate processing position, the gas discharge port and the substrate transfer gate are disposed in this order. A gas restraining member which restrains processing gas for processing the substrate from flowing toward the substrate transfer gate is provided between the gas discharge port and the substrate transfer gate.

Abstract: Uniformity of temperature is established within a wafer, and a higher throughput is achieved while the wafer heating time is dramatically reduced by combining lamp heating with hot-wall heating. Lamps 10 are provided outside the furnace body 3 of a hot-wall CVD apparatus. The hot-wall reactor furnace body 3 is preheated to a prescribed temperature. Wafers W are loaded into the furnace body 3, and these wafers W are rapidly heated mediately thereafter to the desired temperature by light emitted by the lamps 10. The lamps 10 are switched off following heating, and the wafer temperature is allowed to reach a uniform state as a result of heat diffusion in the wafers in the hot-wall reactor furnace body 3. It is also possible to adopt an arrangement in which preheating commensurate with the cooling occurring during the transport period is performed before the wafers W are loaded into the furnace body 3. the wafers W are then loaded into the reactor furnace body 3.
