Apparatus and method for selective deposition
First Claim
1. A substrate processing apparatus, comprising:
- a platform;
a transfer chamber centrally disposed on the platform, wherein at least one robot is disposed within the transfer chamber;
a pre-clean chamber disposed on the platform adjacent the transfer chamber;
an epitaxial deposition chamber disposed on the platform adjacent the transfer chamber;
a surface passivation chamber disposed on the platform adjacent the transfer chamber, the surface passivation chamber having a pedestal disposed therein, the pedestal including a resistive heater;
an atomic layer deposition chamber disposed on the platform adjacent the transfer chamber; and
a microprocessor controller programmed to;
perform, in the pre-clean chamber, a pre-clean process on a substrate disposed in the pre-clean chamber;
transfer, via the at least one robot, without breaking vacuum, the substrate from the pre-clean chamber to the epitaxial deposition chamber;
perform, in the epitaxial deposition chamber, an epitaxial deposition process to deposit source/drain materials on the substrate;
transfer, via the at least one robot, without breaking vacuum, the substrate from the epitaxial deposition chamber to the surface passivation chamber;
perform, in the surface passivation chamber, a surface passivation process to deposit an alkyl silyl material on dielectric materials disposed on the substrate;
transfer, via the at least one robot, without breaking vacuum, the substrate from the surface passivation chamber to the atomic layer deposition chamber; and
perform, in the atomic layer deposition chamber, a deposition operation to form a capping layer on the source/drain materials.

Abstract
Methods and apparatus for processing a substrate are described herein. Methods for passivating dielectric materials include forming alkyl silyl moieties on exposed surfaces of the dielectric materials. Suitable precursors for forming the alkyl silyl moieties include (trimethylsilyl)pyrrolidine, aminosilanes, and dichlorodimethylsilane, among others. A capping layer may be selectively deposited on source/drain materials after passivation of the dielectric materials. Apparatus for performing the methods described herein include a platform comprising a transfer chamber, a pre-clean chamber, an epitaxial deposition chamber, a passivation chamber, and an atomic layer deposition chamber.
