    摘要: A semiconductor device is constructed so that an insulation film is provided in regions other than a protruding portion of a substrate. A polycrystalline silicon layer and a metal silicide layer are formed over said insulation film to provide a multi-layer structure, and a take-out portion for at least one of the emitter, base, and collector members of a bipolar transistor provided in the mesa region is constituted by a film of this multi-layer structure. By virtue of the use of metal silicide together with the polycrystalline silicon, a very low resistance is achieved which enhances the device's operating speed. Further, the metal silicide is separated from the protruding portion of the substrate by a portion of the polycrystalline silicon to provide a smooth interface with the substrate. This smooth interface significantly reduces crystal defects in the single crystal substrate.

    摘要: A bipolar memory of a construction having high immunity from soft error attributable to alpha rays is provided. The transistors of a flip flop, i.e., the essential circuit of the memory cell, are inverted, and the load device thereof has a shielding arrangement for shielding the flip flop from the noise produced within the substrate. Either pnp type transistors or Schottky barrier diodes are employed as the load devices. A buried layer (ordinarily, an n type layer) and a doped layer of the reverse conductivity type (ordinarily the p type) are formed in the region where the device is provided. A reverse bias is applied across the buried layer and the doped layer to shut off the noise produced within the substrate.

    摘要: A bipolar transistor capable of operating at high speeds. In a bipolar transistor designed for operation at high speeds, a polycrystalline silicon layer used as a base electrode effects is a contact area with respect to the base region which lacks precision or tends to increase. Further, when the transistor is formed in a small size, the ratio of the contact area with respect to the polycrystalline area increases, making it difficult to increase the operation speed. In order to reduce the contact area of the polycrystalline silicon layer, this invention deals with the structure in which the polycrystalline silicon layer is brought into contact with a portion near the edge of the convex semiconductor layer maintaining a small size and a high precision.
