Abstract
The present disclosure provides a method of forming a semiconductor device structure with selectively fabricating semiconductor device structures having fully silicided (FuSi) gates and partially silicided gates. In aspects of the present disclosure, a semiconductor device structure with a first semiconductor device and a second semiconductor device is provided, wherein each of the first and second semiconductor devices includes a gate structure over an active region, each of the gate structures having a gate electrode material and a gate dielectric material. The gate electrode material of the first semiconductor device is recessed, resulting in a recessed first gate electrode material which is fully silicided during a subsequent silicidation process. On the gate electrode material of the second semiconductor device, a silicide portion is formed during the silicidation process.
