    摘要: A technique for doping silicon (100) material or other semiconductors (100, 200) uses gas phase dopant sources under reduced pressure in a radiantly heated (11), cold-wall reactor (10). The technique is applied to the automated integrated circuit manufacturingtechniques being adopted in modern fabrication facilities. The method includes placing a substrate (20) comprising semiconductor material on a thermally isolated support structure (18, 19) in a reduced pressure, cold-wall (25) reaction chamber (10); radiantly heating (11) the substrate (20) within the reaction chamber (10) to a controlled temperature; flowing a gas phase source of dopant at controlled pressure and concentration in contact with the substrate (20) so that the dopant is absorbed by the substrate (20) and annealing the substrate (20). The substrate (20) may be first coated with a layer of polycrystalline (105) semiconductor, and then gas phase doping as described above may be applied to the polycrystalline layer (105).

    摘要: A vertical bipolar transistor structure has an extrinsic base region (4) covered by a metal silicide (eg WSi 2 ) layer (6) and a doped (eg with boron) polysilicon layer (7). The metal silicide and polysilicon layers (6, 7) have an opening therein with which the emitter (3) and intrinsic base region (2) of the transistor are aligned. The vertical bipolar transistor structure can be produced by a method including delimiting a transistor area in a semiconductor substrate, depositing in succession over the the transistor area a silicide layer (6), a doped polysilicon layer (7) and a silicon dioxide layer (8), forming an aperture through the silicon dioxide, the doped polysilicon and the silicide layers, forming an insulating layer (8A) over the transistor area and driving in dopant from the polysilicon layer to form an extrinsic base region (4), removing the insulating layer from the base of the aperture but not from the sidewall of the aperture and forming an intrinsic base region and an emitter aligned with the aperture and the extrinsic base region.

    摘要: A semiconductor body (1) is provided having a first region (4) of one conductivity type adjacent one major surface (2). An insulating layer (5) is formed on the one major surface and masking means (6,7) are used to form over first and second areas (20 and 21) of the one major surface (2) windows (8,9,10) in the insulating layer (5) through which impurities are introduced to form a relatively highly doped region (11) of the opposite conductivity type adjacent the first area (20) and a relatively lowly doped region (12) of the opposite conductivity type adjacent the second area (21). The surface (5a) of the insulating layer (5) is exposed prior to introducing impurities of the one conductivity type for forming a region (13) within the relatively lowly doped region (12) of the opposite conductivity type and with a dose sufficient to form the region (13) but not sufficient to overdope the relatively highly doped region (11) so avoiding the need to mask the first area (20) during this step. The thickness of the insulating layer (5) is such that a proportion of the impurities of the one conductivity type penetrate the insulating layer (5) to increase the doping of a surface layer (40) of the first region (4) so as to reduce problems such as punch-through effects.

    摘要: There is disclosed a method of manufacturing a semiconductor device comprising the steps of forming a polysilicon film (13) on a semiconductor substrate (11) through an oxidation film (12), forming a mask (14) of a predetermined pattern on the polysilicon film, forming a molybdenum film (17) on the polysilicon film and silicifying those regions (18 1 , 18.) of said molybdenum film (17) not covered by the mask so that a structure of the uncovered molybdenum film regions (18 1 , 18 2 ) and those regions (15 1 , 15 2 ) of the polysilicon film located under the uncovered molybdenum regions have low resistance, while a region (16) of the molybdenum film covered by the mask have high resistance.
