    Abstract: A new solid state field effect bipolar device provides for high current gain and low input capacitance, while avoiding the "punch-through" effects that limit the downward scaling of conventional bipolar and field effect devices. The device typically compromises a metallic (e.g. a metal or silicide) emitter, which makes ohmic contact to a semi-insulator; a channel terminal which contacts an inversion layer formed at the interface between the semiinsulator and a semiconductor depletion region; and a collector, which is the semiconductor bulk. The novel device controls the flow of majority carriers from the emitter into the collector by the biasing action of charge in the inversion channel. The technique can be utilized in making a transistor, photodetector, thyristor, controlled optical emitter, and other devices.

    Abstract: A collector (204) is deposited and a base (222) grown on the collector (204), for example, epitaxially depositing either silicon or silicon germanium. An emitter (230) is fabricated on the base (222) followed by implant doping an extrinsic base region (224), using for example, boron. The extrinsic base region (224) doping diffuses out during subsequent thermal processing steps in chip fabrication, creating an out diffusion region (226) in the device, which can adversely affect various operating characteristics, such as parasitic capacitance and linearity. Counter doping using arsenic or phosphorus controls the out diffusion. Also the counter doping can be formed using tilt implanting or, alternatively, by region by implant doping the counter doped region (228) and forming a spacer (not shown) on the base (222) prior to implanting the extrinsic base region (224).

The device structure (14) includes a collector region (18), an intrinsic base formed (22)on the collector region (18), an emitter (74) coupled with the intrinsic base (22) and separated from the collector (18) by the intrinsic base (22), and an isolation region extending through the intrinsic base (22) to the collector region (18). The isolation region is formed with a first section having first sidewalls (29,35) that extend through the intrinsic base (22) and a second section with second sidewalls (31, 33) that extend into the collector region (18). The second sidewalls (31, 33) are inclined relative to the first sidewalls (29, 35.) The isolation region is positioned in a trench (34, 36) that is formed with first and second etching process in which the latter etches different crystallographic directions of a single-crystal semiconductor material at different etch rates.

    Abstract: Disclosed are embodiments of an improved transistor structure (100) (e.g., a bipolar transistor (BT) structure or heterojunction bipolar transistor (HBT) structure) and a method of forming the transistor structure (100). The structure embodiments can incorporate a dielectric layer (130) sandwiched between an intrinsic base layer (120) and a raised extrinsic base layer (140) to reduce collector-base capacitance C cb , a sidewall-defined conductive strap (150) for an intrinsic base layer (120) to extrinsic base layer (140) link-up region to reduce base resistance R b and a dielectric spacer (160) between the extrinsic base layer (140) and an emitter layer (180) to reduce base- emitter C be 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 (130), the width of the conductive strap (150), the width of the dielectric spacer (160) and the width of the emitter layer (180)) to be selectively adjusted in order to optimize transistor performance.
