Abstract:
Various examples of an integrated circuit device and a method for forming the device are disclosed herein. In an example, a method includes receiving a workpiece that includes a substrate, and a device fin extending above the substrate. The device fin includes a channel region. A portion of the device fin adjacent the channel region is etched, and the etching creates a source/drain recess and forms a dielectric barrier within the source/drain recess. The workpiece is cleaned such that a bottommost portion of the dielectric barrier remains within a bottommost portion of the source/drain recess. A source/drain feature is formed within the source/drain recess such that the bottommost portion of the dielectric barrier is disposed between the source/drain feature and a remainder of the device fin.

Claim (Index 15):
A method comprising:\n removing a portion of a fin structure to form a recess in the fin structure, wherein a dielectric barrier is formed in the recess during the removing of the portion of the fin structure; removing a first portion of the dielectric barrier such that a second portion of the dielectric barrier remains in the recess after the removing of the first portion of the dielectric barrier; and forming a source/drain feature within the recess on the second portion of the dielectric barrier.
