The Schottky barrier diode further comprises a first-conductivity-type-doped semiconductor region having a doping of a first conductivity type, which is the opposite of the second conductivity type, on one side of a dummy gate electrode and a Schottky barrier structure surrounded by the doped guard ring on the other side. A Schottky barrier region may be laterally surrounded by the dummy gate electrode and the doped guard ring. The doped guard ring includes an unmetallized portion of a gate-side second-conductivity-type-doped semiconductor region having a doping of a second conductivity type. A Schottky barrier region may be laterally surrounded by a doped guard ring including a gate-side doped semiconductor region and a STI-side doped semiconductor region.

    摘要: Disclosed are embodiments of an improved transistor structure (e.g., a bipolar transistor (BT) structure or heterojunction bipolar transistor (HBT) structure) and a method of forming the transistor structure. The structure embodiments can incorporate a dielectric layer sandwiched between an intrinsic base layer and a raised extrinsic base layer to reduce collector-base capacitance Ccb, a sidewall-defined conductive strap for an intrinsic base layer to extrinsic base layer link-up region to reduce base resistance Rb and a dielectric spacer between the extrinsic base layer and an emitter layer to reduce base-emitter Cbe capacitance. The method embodiments allow for self-aligning of the emitter to base regions and further allow the geometries of different features (e.g., the thickness of the dielectric layer, the width of the conductive strap, the width of the dielectric spacer and the width of the emitter layer) to be selectively adjusted in order to optimize transistor performance.
