INTEGRATED CIRCUIT DEVICE WITH SOURCE/DRAIN BARRIER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240178271 titled 'INTEGRATED CIRCUIT DEVICE WITH SOURCE/DRAIN BARRIER

Simplified Explanation

The abstract describes a method for forming an integrated circuit device by etching a portion of a device fin to create a source/drain recess and forming a dielectric barrier within the recess. The workpiece is then cleaned to leave the dielectric barrier at the bottom of the recess, and a source/drain feature is formed with the dielectric barrier between it and the rest of the device fin.

  • Method for forming an integrated circuit device:
   - Receive a workpiece with a substrate and a device fin
   - Etch a portion of the device fin to create a source/drain recess
   - Form a dielectric barrier within the source/drain recess
   - Clean the workpiece to leave the dielectric barrier at the bottom of the recess
   - Form a source/drain feature with the dielectric barrier between it and the device fin

Original Abstract Submitted

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.
