Semiconductor device and manufacturing method thereof

Image Number 12 for United States Patent #5864161.

A method of manufacturing a semiconductor device includes the steps of forming an insulating film on a silicon region of a substrate having the silicon region on a surface the insulating film having an opening for forming an exposed region of the silicon region, supplying a gas containing a halogen onto the silicon region, and supplying a source gas of silicon onto the silicon region, thereby selectively depositing the silicon on the exposed region of the silicon region.
