Abstract
The semiconductor device includes a first MIS transistor including a gate insulating film, a gate electrodeformed on the gate insulating filmand source/drain regions, a second MIS transistor including a gate insulating filmthicker than the gate insulating film, a gate electrodeformed on the gate insulating film, source/drain regionsand a ballast resistorconnected to one of the source/drain regions, a salicide block insulating filmformed on the ballast resistorwith an insulating filmthinner than the gate insulating filminterposed therebetween, and a silicide filmformed on the source/drain regions
