Abstract
A semiconductor device has: a silicon (semiconductor) substrate; a gate insulating film and a gate electrode, which are formed on the silicon substrate in this order; and source/drain material layers formed in recesses (holes) in the silicon substrate, the recesses being located beside the gate electrode. Here, each of side surfaces of the recesses, which are closer to the gate electrode, is constituted of at least one crystal plane of the silicon substrate.
