Abstract: Methods of fabricating semiconductor devices are provided. The method includes forming a gate dielectric layer over a substrate. The method also includes depositing a first p-type work function tuning layer over the gate dielectric layer using a first atomic layer deposition (ALD) process with an inorganic precursor. The method further includes forming a second p-type work function tuning layer on the first p-type work function tuning layer using a second atomic layer deposition (ALD) process with an organic precursor. In addition, the method includes forming an n-type work function metal layer over the second p-type work function tuning layer.

Abstract: Embodiments disclosed herein relate generally to capping processes and structures formed thereby. In an embodiment, a conductive feature, formed in a dielectric layer, has a metallic surface, and the dielectric layer has a dielectric surface. The dielectric surface is modified to be hydrophobic by performing a surface modification treatment. After modifying the dielectric surface, a capping layer is formed on the metallic surface by performing a selective deposition process. In another embodiment, a surface of a gate structure is exposed through a dielectric layer. A capping layer is formed on the surface of the gate structure by performing a selective deposition process.
