    摘要: Methods of forming a finFET are provided. The methods may include forming a fin-shaped channel region including indium (In) on a substrate, forming a deep source/drain region adjacent to the channel region on the substrate and forming a source/drain extension region between the channel region and the deep source/drain region. Opposing sidewalls of the source/drain extension region may contact the channel region and the deep source/drain region, respectively, and the source/drain extension region may include InyGa1−yAs, and y is in a range of about 0.3 to about 0.5.
