Abstract
Embodiments of the present disclosure provide semiconductor device structures and methods of forming the same. The structure includes a first source/drain region disposed in a PFET region and a second source/drain region disposed in an NFET region. The second source/drain region comprises a dipole region. The structure further includes a first silicide layer disposed on and in contact with the first source/drain region, a second silicide layer disposed on and in contact with the first silicide layer, and a third silicide layer disposed on and in contact with the dipole region of the second source/drain region. The first, second, and third silicide layers include different materials. The structure further includes a first conductive feature disposed over the first source/drain region, a second conductive feature disposed over the second source/drain region, and an interconnect structure disposed on the first and second conductive features.
