    摘要: A method of manufacturing a semiconductor device. In the method, a substrate is prepared, which includes a buried oxide film and a SiGe layer formed on the buried oxide film. Then, heat treatment is performed on the substrate at a temperature equal to or lower than a first temperature, to form a protective oxide film on a surface of the SiGe layer. Next, the substrate having the protective oxide film is heated in a non-oxidizing atmosphere to a second temperature higher than the first temperature. Further, heat treatment is performed on the substrate thus heated, in an oxidizing atmosphere at a temperature equal to or higher than the second temperature, to form oxide the SiGe layer, make the SiGe layer thinner and increasing Ge concentration in the SiGe layer, thus forming a SiGe layer having the increased Ge concentration.

    摘要: In a semiconductor manufacturing apparatus, a semiconductor substrate ion-implanted with an ion species is heated and thereby raised in temperature under vacuum. At this time, a partial pressure of a gas released from the semiconductor substrate is measured by a quadrupole mass spectrometer. Further, a change in partial pressure with time is observed and compared with a pre-measured release characteristic, whereby the temperature of the semiconductor substrate is corrected.

    摘要: A device isolation region made up of a silicon oxide film, which is perfectly isolated up to the direction of the thickness of an SOI silicon layer, and an activation region of the SOI silicon layer, whose only ends are locally thinned, are formed on an SOI substrate. A source diffusion layer and a drain diffusion layer of a MOS field effect transistor in the activation region are provided so that according to the silicidization of the SOI silicon layer subsequent to the formation of a high melting-point metal, a Schottky junction is formed only at each end of the activation region and a PN junction is formed at a portion other than each end thereof.
