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

Claim 14:
15. A method of forming a semiconductor structure without breaking a vacuum, the method comprising:
cleaning a substrate to form a substrate surface substantially free of oxide, the substrate surface comprising 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;
performing a first operation on the substrate surface, the first operation comprising exposing the substrate surface to a first molybdenum precursor and exposing the substrate surface to a reactant to selectively deposit a first molybdenum film on the bottom surface;
treating the bottom surface to form or deposit one or more of a cap and a liner; and
annealing the substrate.
