摘要: In the method for fabricating a semiconductor device of the present invention, a collector layer of a first conductivity type is formed in a region of a semiconductor substrate sandwiched by device isolation. A collector opening is formed through a first insulating layer deposited on the semiconductor substrate so that the range of the collector opening covers the collector layer and part of the device isolation. A semiconductor layer of a second conductivity type as an external base is formed on a portion of the semiconductor substrate located inside the collector opening, while junction leak prevention layers of the same conductivity type as the external base are formed in the semiconductor substrate. Thus, the active region is narrower than the collector opening reducing the transistor area, while minimizing junction leak.

摘要: A silicon oxide film 102, a Pt film 103x, a Ti film 104x and a PZT film 105x are deposited in this order over a Si substrate 101. The Si substrate 101 is placed in a chamber 106 so that the PZT film 105x is irradiated with an EHF wave 108. The irradiation with the EHF wave locally heats a dielectric film such as the PZT film. As a result, it is possible to improve, for example, the leakage property of the dielectric film without adversely affecting a device formed on the Si substrate 101.

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.
