Abstract: A semiconductor device includes a fin structure disposed on a substrate, a shallow-trench isolation (STI) region on opposite sides of the fin structure, dielectric fin sidewall structures extending along sides of the fin structure and extending from a top of the STI region partially up the fin structure, and a source/drain region disposed within an upper portion of the fin structure. A bottom surface of the source/drain region contacts a top surface of the dielectric fin sidewall.

Abstract: A method for fabricating a semiconductor device includes forming a doped semiconductor layer on a substrate and forming a fin structure disposed on the doped semiconductor layer. The fin structure is doped with a p-type dopant. The method further includes forming a source/drain region within an upper portion of the fin structure and forming a fin sidewall along a lower portion of the fin structure. The fin sidewall has the p-type dopant.

Abstract: Systems and methods are provided for fabricating a semiconductor structure including sidewall spacers. An example semiconductor structure includes: a gate structure, a first sidewall spacer, and a second sidewall spacer. The gate structure is formed over a substrate. The first sidewall spacer is adjacent to the gate structure, a top part of the first sidewall spacer including a first dielectric material, a bottom part of the first sidewall spacer including a second dielectric material. The second sidewall spacer is adjacent to the first sidewall spacer, the second sidewall spacer including a third dielectric material.

Abstract: A system is configured to perform plasma related fabrication processes. The system includes a process chamber and a wafer stage positioned within the process chamber. The wafer stage is configured to secure a process wafer. The system further includes a bottom electrode positioned beneath the wafer stage, a top electrode positioned external to the chamber, and a plasma distribution mechanism. The plasma distribution mechanism is reconfigurable to allow for more than one plasma distribution profile.
