Abstract

A method for fabricating a semiconductor device is disclosed. A fin is formed on a substrate. The fin protrudes from a trench isolation layer on a substrate. The fin comprises a source region, a drain region and a channel region therebetween. A dummy gate strides across the fin and surrounding the channel region. An upper portion of the fin is removed so as to form a hollow channel underneath the dummy gate. A replacement channel layer is in-situ epitaxially grown in the hollow channel.
