    摘要: A ring-shaped emitter region is formed either in a region a little toward an inner periphery or in a region a little toward an outer periphery in an upper layer portion of a ring-shaped base region of a bipolar transistor. A conductive layer is laminated through an insulating layer in a region surrounded by the ring-shaped emitter region provided a little toward the inner periphery of the base region, a conductive side wall is formed on the sides of the conductive layer and the insulating layer, and the ring-shaped emitter region and the conductive layer are connected through the conductive side wall. A metallic emitter electrode is connected to the conductive layer. On the other hand, in a region surrounded by the ring-shaped base region in which the ring-shaped emitter region is formed a little toward the outer periphery, a conductive layer is laminated through an insulating layer, a conductive side wall is formed on the sides of the conductive layer and the insulating layer, and the ring-shaped base region and the conductive layer are connected through the conductive side wall. A metallic base electrode is connected to the conductive layer. Since an emitter region and a collector region have the same conduction type in a bipolar transistor, such a bipolar transistor that has a construction in which the emitter described above is used as a collector is also available.

    摘要: Semiconductor-device fabricating steps include the steps of forming a first conducting film serving as an electrode on a substratum semiconductor layer through an insulating film, forming an opening in partial regions of the first conducting film and the insulating film, and thereafter forming a second conducting film for connecting the first conducting film with the substratum semiconductor layer on the inner periphery or in the vicinity of the opening, then forming a second electrode in the opening through an insulating side wall, moreover patterning the first conducting film before selectively etching and removing the insulating film under the first conducting film, and thereby forming a space between the first conducting film and the substratum semiconductor layer. Moreover, the semiconductor-device fabrication steps include the steps of patterning the first insulating film and first conducting film formed in order on the substratum semiconductor layer to from an electrode made of the first conducting film, thereafter covering the whole with a second insulating film, then patterning the second insulating film to form an opening in a region including an electrode, selectively etching and removing the first insulating film under the electrode through the opening, and thereby forming a space between the electrode and substratum semiconductor layer.
