    摘要: A semiconductor layer 30 of a graded SiGe-HDTMOS is constructed of an upper Si film 12, an Si buffer layer 13, an Si1−xGex film 14 and an Si cap layer 15. The region between a source region 20a and drain region 20b of the semiconductor layer 30 includes a high concentration n-type Si body region 22 and an n Si region 23, an Si cap region 25 and an SiGe channel region 24. A Ge composition ratio x of the Si1−xGex film 14 is made to increase from the Si buffer layer 13 to the Si cap layer 15. For the p-type HDTMOS, the electron current component of the substrate current decreases.

    摘要: The bipolar transistor of the present invention includes a Si collector buried layer, a first base region made of a SiGeC layer having a high C content, a second base region made of a SiGeC layer having a low C content or a SiGe layer, and a Si cap layer 14 including an emitter region. The C content is less than 0.8% in at least the emitter-side boundary portion of the second base region. This suppresses formation of recombination centers due to a high C content in a depletion layer at the emitter-base junction, and improves electric characteristics such as the gain thanks to reduction in recombination current, while low-voltage driving is maintained.

    摘要: A crystal growing apparatus comprises a vacuum vessel, a heating lamp, a lamp controller for controlling the heating lamp, a gas inlet port, a flow rate adjuster for adjusting the flow rate of a gas, a pyrometer for measuring the temperature of a substrate, and a gas supply unit for supplying a Si2H6 gas or the like to the vacuum vessel. An apparatus for ellipsometric measurement comprises: a light source, a polariscope, a modulator, an analyzer, a spectroscope/detector unit, and an analysis control unit for calculating &PSgr;, &Dgr;. In removing a chemical oxide film on the substrate therefrom, in-situ ellipsometric measurement allows a discrimination between a phase 1 during which a surface of the substrate is covered with the oxide film and a phase 2 during which the surface of the substrate is partially exposed so that the supply of gas suitable for the individual phases is performed and halted.

    摘要: In a bipolar transistor block, a base layer (20a) of SiGe single crystals and an emitter layer (26) of almost 100% of Si single crystals are stacked in this order over a collector diffused layer (9). Over both edges of the base layer (20a), a base undercoat insulating film (5a) and base extended electrodes (22) made of polysilicon are provided. The base layer (20a) has a peripheral portion with a thickness equal to that of the base undercoat insulating film (5a) and a center portion thicker than the peripheral portion. The base undercoat insulating film (5a) and gate insulating films (5b and 5c) for a CMOS block are made of the same oxide film. A stress resulting from a difference in thermal expansion coefficient between the SiGe layer as the base layer and the base undercoat insulating film 5a can be reduced, and a highly reliable BiCMOS device is realized.
