Abstract

In the scope of thesis, selective epitaxial growth of monocrystal silicon-germanium-carbon (SiGeC) and monocrystal silicon (SiCap) were deposited on silicon substrate at low temperature by using reduced pressure chemical vapor deposition (RPCVD) technique. Silane as silicon source, german as germanium source, diborane as boron source and metilsilane as carbon source were used at film deposition. SiGeC and SiCap films were applied SiGeC HBT (Silicon-Germanium-Carbon Heterojunction Bipolar Transistor) technology which is the first step of 0,25 µm SiGeC BiCMOS (Silicon-Germanium-Carbon Bipolar Complementray Metal Oxide Semiconductor) process technology and electrical performance of the films in the transistor was evaluated. At the first step ...
