    摘要： A bipolar transistor with raised extrinsic base and selectable self-alignment between the extrinsic base and the emitter is disclosed. The fabrication method may include the formation of a predefined thickness of a first extrinsic base layer of polysilicon or silicon on an intrinsic base. A dielectric landing pad is then formed by lithography on the first extrinsic base layer. Next, a second extrinsic base layer of polysilicon or silicon is formed on top of the dielectric landing pad to finalize the raised extrinsic base total thickness. An emitter opening is formed using lithography and RIE, where the second extrinsic base layer is etched stopping on the dielectric landing pad. The degree of self-alignment between the emitter and the raised extrinsic base is achieved by selecting the first extrinsic base layer thickness, the dielectric landing pad width, and the spacer width.

    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.

The device structure includes an epitaxial semiconductor region having the second crystalline orientation and first and second p-n junctions in the epitaxial semiconductor region. The epitaxial semiconductor region extends from the second semiconductor layer through the insulating layer and the first semiconductor layer toward a top surface of the first semiconductor layer. The first and second p-n junctions are arranged in depth within the epitaxial semiconductor region between the second semiconductor layer and the top surface of the first semiconductor layer.

    摘要： Disclosed is a method for increasing substrate resistance in a silicon controlled rectifier in order to decrease turn on time so that the silicon controlled rectifier may be used as an effective electrostatic discharge protection device to protect against HBM, MM and CDM discharge events. Additionally, disclosed is an improved SCR structure that is adapted for use as an electrostatic discharge device to protect against human body model events by delivering an electrostatic discharge current directly to a ground rail. The improved SCR structure incorporates various features for increasing substrate resistance and, thereby, for decreasing turn on time. These features include a second n-well that functions as an obstacle to current flow, a narrow current flow channel between co-planar buried n-bands connected to a lower portion of the second n-well, a zero threshold voltage area, and an external resistor electrically connected between the SCR and the ground rail.
