Öz

The research on Sı/SiGe heterojunction bipolar transisfors has led the

ultra-high-speed transıstors tha! are compatible wilh the state-of-the-art silicon

inlegraled technology. The SiGe base regions ofthese transistors are grımn selectivety

on silicon substrates. Self-aligned slructures are used to reduce the external base

resisıance aııd base colleclor parasitic capacitance. The germanium profile in Ihe base

is graded to obtain a drift ejfect to reduce the base-transil tiıne. Si/SiGe integrated

circuils for applications in optical-flber link systems and Si/SiGe microwave pover

Iransistors have been produced wilh remarkable speeds. The SiGe semıconduaor

material system, HBT slructures and fabricalion, and device performance issues are

reviewed in thispaper.
