Abstract
A method for growing the high quality strained epitaxial heterostructure as well as the fabrication of Si1-xGex-channel pMOSFET containing a high Ge fraction layer have been investigated. It is found that lowering deposition temperature of the Si1-xGex and Si capping layers is necessary with increasing Ge fraction in order to prevent an island growth of the heterostructure. Using optimized Si/Si1-xGex/Si heterostructures with flat surfaces and interfaces, high performance Si0.5Ge0.5-channel pMOSFET has been achieved with the large mobility enhancement of about 70% at 300K and over 150% at 77K compared with those of MOSFET without Si1-xGex-channel.
