    摘要: A semiconductor device includes a plurality of semiconductor regions of a first conductive type and a plurality of semiconductor regions of a second conductive type. AMOS transistor having a channel of the second conductive type is formed in the semiconductor regions of the first conductive type, and a bipolar transistor and a MOS transistor having a channel of the first conductive type are formed in the semiconductor regions of the second conductive type. Each of the semiconductor regions of the first conductive type is made up of a semiconductor layer where the impurity concentration decreases with the depth from the surface thereof, a first buried layer of the first conductive type which is formed in a semiconductor substrate and where the impurity concentration distribution in the direction of thickness has a single peak value, and a second buried layer of the first conductive type which is formed between the semiconductor layer and the first buried layer and where the impurity concentration distribution in the direction of thickness has a single peak value. The first and second buried layers are formed by the ion implantation method, after an epitaxial growth process and a field oxidation process have been completed.

    摘要: In a method of fabricating a semiconductor device having a MISFET and/or bipolar transistor and/or a resistor formed with different surface portions of a single silicon semiconductor substrate in which a silicide layer is formed on each of source/drain regions of the MISFET and/or collector contact region and extrinsic base region of the bipolar transistor and/or contact regions of the resistor, the bipolar transistor has its emitter region formed by diffusing an impurity contained in doped polysilicon film serving as an emitter electrode of the bipolar transistor into a part of its base region. The resistor may have a resistive region formed in a surface portion of the substrate and may be covered with an insulating film and a doped polysilicon film thereon or may have a doped polysilicon film formed over a surface portion of the substrate as a resistor element. These doped polysilicon films in the resistor are films which are formed in the same step as that for the doped silicon film serving as the emitter electrode in the bipolar transistor. Each of the doped polysilicon film in the bipolar transistor and that in the resistor are covered with an insulating film before a refractory metal film is formed over a whole surface of the substrate to prevent formation of silicide films on the doped polysilicon films in the bipolar transistor and resistor.
