摘要:
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.

A method and system for providing a bipolar transistor is described. The method and system include providing a compound base region including includes a compound box extension, providing an emitter region, and providing a collector region. The emitter region is coupled with the base region. The SiGe base region is coupled with the collector region and includes a SiGe box extension. The box extension resides substantially between the emitter and the heterogeneous base region.

Disclosed herein are devices, methods and systems for implementing gettering layers. Devices including gettering layers can be implemented such that a gettering layer doped with carbon, boron, fluorine or any other appropriate impurity is formed on a semiconductor substrate, a device layer is formed on the gettering layer, and a device region is formed in the device layer having a depth that maintains a distance in the device layer between the gettering layer and the device region.
