Patent Primary Examiner
A semiconductor device including source/drain contacts extending into source/drain regions, below topmost surfaces of the source/drain regions, and methods of forming the same are disclosed. In an embodiment, a semiconductor device includes a semiconductor substrate; a first channel region over the semiconductor substrate; a first gate stack over the semiconductor substrate and surrounding four sides of the first channel region; a first epitaxial source/drain region adjacent the first gate stack and the first channel region; and a first source/drain contact coupled to the first epitaxial source/drain region, a bottommost surface of the first source/drain contact extending below a topmost surface of the first channel region.
