Abstract :
A one-growth step fabrication scheme for strained Ge FinFET structures has been successfully developed and implemented in a device fabrication scheme. From device point of view, the concept including two growth steps might be even more favorable. However, it requires an improvement of the pre-epi oxide removal from Si1-xGex surfaces.
