    摘要: In a method of manufacturing a semiconductor device according to the present invention, a given position of a thermal oxide film formed on a monocrystalline silicon layer is opened to expose a surface of the monocrystalline silicon layer to serve as a getter site, a polycrystalline silicon layer is deposited on the thermal oxide film and the surface of the monocrystalline silicon layer, and the polycrystalline silicon layer is oxidized to convert the surface of the monocrystalline silicon layer directly contacting the polycrystalline silicon layer into an oxide film by thermal oxidation. That is, the position of interface between the oxide film and the monocrystalline silicon layer is shifted into the original monocrystalline silicon layer. During thermal oxidation of the polycrystalline silicon layer, a plurality of crystal defects to serve as getter sites are generated deeper than those generated by a conventional implagetter method in the monocrystalline silicon layer. In addition, the crystal defects generated in the manner described above do not extend to the surrounding region by subsequent annealing so that a region of the crystal defects is limited.

    摘要: This invention discloses a method of manufacturing an SST bipolar transistor, and the manufacturing method is capable of defining the size of a base region of the SST bipolar transistor. An insulating film and a spacer film serving as a spacer are sequentially formed in a bipolar transistor forming region on the main surface of a semiconductor substrate. Thereafter, the spacer film is patterned into a spacer film pattern for defining the size of the base region. A second insulating film, a base electrode pattern and a third insulating film are sequentially formed on the spacer film pattern. A first opening which reaches the spacer film pattern through the second insulating film, the base electrode pattern and the third insulating film is formed. The spacer film pattern is etched from the first opening to form a second opening having a diameter larger than that of the first opening. The insulating film exposed in the second opening is etched. The size of the base region on the major surface of the semiconductor substrate is defined by the size of the second opening.

An impurity is doped in a semiconductor substrate through the opening formed in the field oxide film to form external base region.

    摘要: Manufacturing a double polysilicon layer self-aligned type bipolar transistor. A polysilicon layer for emitter impurity diffusion is formed prior to the formation of a polysilicon layer for leading out a base. A first polysilicon layer containing impurities for base impurity diffusion is deposited over the entire surface of a semiconductor structure. After the first polysilicon layer is patterned into a predetermined shape, an intrinsic base layer is formed by thermally diffusing impurities from a base impurity diffusion source. Subsequently, a second polysilicon layer containing emitter impurities is formed over the base impurity diffusion source, and then patterning is performed such that the first and second polysilicon layers remain in a region narrower than the base impurity diffusion source. Thereafter, an emitter layer is formed by thermal diffusion.
