Assignee: APPLIED MATERIALS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method of forming a semiconductor structure, the method comprising:
cleaning a substrate to form a substrate surface substantially free of oxide, the substrate including at least one feature having a bottom surface and a sidewall surface, the bottom surface comprising silicon germanium (SiGe), and the sidewall surface comprising a dielectric material;
exposing the substrate surface to a first molybdenum precursor;
exposing the substrate surface to a reactant to selectively deposit a first molybdenum film on the bottom surface; and
forming a cap layer on the first molybdenum film or treating the first molybdenum film to form the cap layer, the cap layer comprising a metal nitride, a PVD metal, or combinations thereof,
the method performed in a processing chamber without breaking vacuum.
