    Abstract: A high fT and fmax bipolar transistor (100) includes an emitter (104), a base (120), and a collector (116). The emitter has a lower portion (108) and an upper portion (1.12) that extends beyond the lower portion. The base includes an intrinsic base (140) and an extrinsic base (144). The intrinsic base is located between the lower portion of the emitter and the collector. The extrinsic base extends from the lower portion of the emitter beyond the upper portion of the emitter and includes a continuous conductor (148) that extends from underneath the upper portion of the emitter and out from underneath the upper portion of the emitter. The continuous conductor provides a low electrical resistance path from a base contact (not shown) to the intrinsic base. The transistor may include a second conductor (152) that does not extend underneath the upper portion of the emitter, but which further reduces the electrical resistance through the extrinsic base.

    Abstract: A heterobipolar transistor (HBT) for high-speed BiCMOS applications is provided in which the collector resistance, Rc, is lowered by providing a buried refractory metal silicide layer underneath the shallow trench isolation region on the subcollector of the device. Specifically, the HBT of the present invention includes a substrate (12) including at least a subcollector (13); a buried refractory metal silicide layer (28) located on the subcollector; and a shallow trench isolation region (30) located on a surface of the buried refractory metal silicide layer. The present invention also provides a method of fabricating such a HBT. The method includes forming a buried refractory metal silicide underneath the shallow trench isolation region on the subcollector of the device.

    Abstract: Methods for fabricating bipolar junction transistors, bipolar junction transistors made by the methods, and design structures for a bipolar junction transistor. The bipolar junction transistor (80) includes a dielectric layer (32) on an intrinsic base (84) and an extrinsic base (82) at least partially separated from the intrinsic base by the dielectric layer. An emitter opening (52) extends through the extrinsic base and the dielectric layer. The dielectric layer is recessed laterally relative to the emitter opening to define a cavity (60a, 60b) between the intrinsic base and the extrinsic base. The cavity is filled with a semiconductor layer (64) that physically links the extrinsic base and the intrinsic base together.
