This invention provides a technique advantageous to improve the operating speed of an integrated circuit. In a semiconductor device in which an n-type transistor and a p-type transistor are formed on the (551) plane of silicon, the thickness of a silicide layer which is in contact with a diffusion region of the n-type transistor is smaller than that of a silicide layer which is in contact with a diffusion region of the p-type transistor. |
