  • Semiconductor fuse structure
    Patent number: 5759877
    Abstract: A semiconductor structure comprising a polysilicon pad, a metal pad separated from the polysilicon pad by an insulator, and a metal via connecting the pads. A fuse is formed at the intersection of the polysilicon pad and via.
    Type: Grant

  • High frequency integrated circuit channel capacitor
    Patent number: 4866567
    Abstract: A high frequency integrated circuit channel capacitor structure comprised of interdigitated field effect transistor gate electrodes and source/drain regions of minimum dimension and respective common connection. The multiplicity of parallel connected capacitive regions between the polysilicon gate electrode and a channel region in the substrate provide precisely controlled capacitors with exceptionally low resistance. Metallization contacts to the gate polysilicon and source/drain regions at each interleaved pattern, together with minimum channel length dimensions, minimizes the capacitive resistance. A CMOS configuration is also feasible.
