    摘要: A method of producing a bipolar transistor comprises the steps of forming a base region (41), forming a high-melting-point metal layer (42) of a base electrode on the base region (41), forming a first insulating layer (43) on the metal layer (42), and selectively etching the first insulating layer (43) and the metal layer (42) to form an opening (45). A second insulating layer (46) is formed on the sides of the first insulating layer (43) and the metal layer (42) within the opening (45), the second insulating layer (46) defining an emitter-providing region. impurities are introduced into the base region (41) by using the second insulating layer (43) as a mask to form an emitter region (49). An emitter electrode (51) and the base electrode (42) are arranged in a like multilayer structure.

    摘要: Planarization of an insulating layer (10) formed on a lower wiring layer (8-6, 8-4, 8-2) and having steps at the shoulders of the wiring patterns, can be attained. On a lower wiring layer (8-6, 8-4, 8-2), a lower insulating layer (10) is formed and a heat resistive material (16) is coated over the lower insulating layer, to form a substantially planar top surface and to fill cavities (22) appearing in the surface of the , lower insulating layer with material (16). Then, etching is carried out to preserve the profile of the surface of the coating layer (16) and to remove the coating layer at portions (18) where through-holes (26) are to be formed. The cavities (22) are still filled with the material (16) after etching. An upper insulating layer (24) is deposited on the exposed lower insulating layer (10) and the remaining part of the coating layer (16). Through-holes (26) and an upper wiring layer (28) are formed. Thus, the upper wiring layer (28) has no contact with the remaining part of the coating layer (16) and the remaining part of the coating layer is never externally exposed.

    摘要: Using a single mask pattern (36,37) on a semiconductor substracte (31), a doped base contact region (39) adjacent the surface of the.substrate, a buried insulating region (38) below the base contact region, and an insulating layer (40) on the base contact region are formed. Optionally, a metal or metal silicide base-electrode-taking-out is formed on the base contact region. Doped emitter (44) and intrinsic base (41) regions are formed below the mask pattern. A collector region (33) is defined by the base contact region and the buried insulating layer to be therebetween i.e. below the mask pattern. Hence, the bipolar transistor formed thereby has a size which is no larger than necessary, thereby reducing the collector-base capacitance, the base resistance, and the size of the device.

    摘要: A semiconductor device of transistors, each of which is surrounded with a field oxide film (7), uses a dielectric isolation structure of a groove filled with an insulating material (15) instead of a PN junction isolation stucture. The field oxide film (7) is formed by selectively oxidizing an epitaxial layer (3), then the groove extending through the epitaxial layer (3) and a buried layer (2) is formed. After the surface of the groove is covered with an insulating film, e.g., a thermal oxide film (14) by oxidizing the surface, the groove is filled with the filler material (15).
