Claim Text:
1. A method, comprising: forming a placeholder source/drain contact structure above a semiconductor material; performing a conformal deposition process to form a liner layer above said placeholder source/drain contact structure; forming a dielectric layer above said liner layer; performing a first planarization process to remove material of said dielectric layer and expose a first top surface of said liner layer above said placeholder source/drain contact structure; forming a first cap layer above said dielectric layer and said first top surface; performing a second planarization process to remove material of said first cap layer and said liner layer to expose a second top surface of said placeholder source/drain contact structure; removing said placeholder source/drain contact structure to define a source/drain contact recess in said dielectric layer, wherein sidewalls of said dielectric layer in said source/drain contact recess are covered by said liner layer; and forming a conductive material in said source/drain contact recess.
