The indu- ced stress by SiGe material in the S/D areas creates a uniaxial strain which enhances hole carrier mobility in the channel region of tran- sistors [1–2]. Webintroducing strain. Two promising candidates that have resulted from this research use an SiGe crys-tal to form a strained channel structure. One is a strained Si channel structure grown on a relaxed SiGe buffer layer of several microns that has threading dislocations at a density of 104 to 106 cm-2.1),2) Although, especially in n-MOSFETs,
WebHigh-speed, low voltage Silicon-Germanium (SiGe) heterojunction bipolar transistors (HBTs) have been designed, fabricated, electrically characterized and modeled. The SiGe HBTs are suitable for use in radio frequency (RF) integrated circuit (IC) applications and were fabricated using non-selective epitaxial growth.
WebGe vertical heterostructures grown on deeply-patterned Si(001) were first obtained in 2012 (C.V. Falub et al., Science2012, 335, 1330–1334), immediately capturing attention due to the appealing possibility of growing micron-sized Ge crystals largely free of thermal stress and hosting dislocations only in a small fraction of their volume.
