摘要:
A semiconductor device of this invention includes: a semiconductor substrate; a gate electrode formed on the semiconductor substrate; a pair of source and drain electrodes respectively formed in regions of the semiconductor substrate situated on opposite sides of the gate electrode in a plan view; and a germanium-containing channel layer situated below the gate electrode to sandwich an gate insulator therebetween and intervening between the pair of source and drain electrodes, wherein a silicide layer forming at least a part of the source and drain electrodes has a lower germanium concentration than the channel layer.
