Abstract
A memory embedded semiconductor device according to the present invention has a memory region having a memory transistor and a logic region having a logic transistor each provided in a common semiconductor substrate. The logic transistor has a gate electrode provided on the semiconductor substrate and source/drain diffusion layers formed in the semiconductor substrate each having a silicide film formed thereon. On the other hand, the memory transistor has a gate electrode provided on the semiconductor substrate and source/drain diffusion layers formed in the semiconductor substrate each having a silicide film formed thereon to be thinner than the silicide film formed on each of the source/drain diffusion layers of the logic transistor.
