Abstract: A method for pseudomorphic growth and integration of an in-situ doped, strain-compensated metastable compound base into an electronic device, such as, for example, a SiGe NPN HBT, by substitutional placement of strain-compensating atomic species. The invention also applies to strained layers in other electronic devices such as strained SiGe, Si in MOS applications, vertical thin film transistors (VTFT), and a variety of other electronic device types. Devices formed from compound semiconductors other than SiGe, such as, for example, GaAs, InP, and AlGaAs are also amenable to beneficial processes described herein.

Abstract: A method, and a resulting device, for fabricating a heterojunction bipolar transistor (HBT). HBT devices have a high transconductance typical of bipolar devices and are additionally capable of high-power operation. To achieve the aforementioned characteristics, HBT devices are generally of the npn type, preferably with a thin, heavily doped base. The thin, heavily doped base maintains a low base-spreading resistance, leading to a high maximum oscillation frequency. In order to maintain a high doping concentration while minimizing outdiffusion of the dopant material, carbon is remotely doped into the base region. Details of the carbon dopant techniques and procedures are described with respect to fabrication of an exemplary HBT device.
