Abstract:
A method including providing a device including a gate structure and a source/drain feature adjacent to the gate structure. An insulating layer (e.g., CESL, ILD) is formed over the source/drain feature. A trench is etched in the insulating layer to expose a surface of the source/drain feature. A semiconductor material is then formed in the etched trench on the surface of the source/drain feature. The semiconductor material is converted to a silicide.
