    Abstract: Methods for forming semiconductor devices, such as FinFETs, are provided. In an embodiment, a fin structure processing method includes removing a portion of a first fin of a plurality of fins formed on a substrate to expose a surface of a remaining portion of the first fin, wherein the fins are adjacent to dielectric material structures formed on the substrate; performing a deposition operation to form features on the surface of the remaining portion of the first fin by depositing a Group III-V semiconductor material in a substrate processing environment; and performing an etching operation to etch the features with an etching gas to form a plurality of openings between adjacent dielectric material structures, wherein the etching operation is performed in the same chamber as the deposition operation.

    Abstract: Implementations described herein generally provide a method of processing a substrate. Specifically, the methods described are used for cleaning and etching source/drain regions on a silicon substrate in preparation for precise Group IV source/drain growth in semiconductor devices. Benefits of this disclosure include precise fin size control in devices, such as 10 nm FinFET devices, and increased overall device yield. The method of integrated clean and recess includes establishing a low pressure processing environment in the processing volume, and maintaining the low pressure processing environment while flowing a first gas over a substrate in a processing volume, depositing a salt on the substrate, heating the processing volume to greater than 90° C., purging the processing volume with a second inert gas, and recessing a source/drain region disposed on the substrate.
