Patent
Methods and systems to enhance process uniformity
TL;DR: In this paper, a semiconductor processing chamber may include a remote plasma region and a processing region fluidly coupled with the remote plasma regions, and the processing region may be configured to house a substrate on a support pedestal.
Patent

TL;DR: In this article, a system, chambers, and processes are provided for controlling process defects caused by moisture contamination in a vacuum or controlled environment, and the chambers may include configurations to provide additional processing capabilities in combination chamber designs.
Patent
Selective etch of silicon nitride
TL;DR: In this article, a method of etching silicon nitride on patterned heterogeneous structures is described and includes a remote plasma etch formed from a fluorine-containing precursor and a nitrogen-and-oxygen-containing precursors.
Patent
Dry-etch for selective tungsten removal
TL;DR: In this paper, a remote plasma etch formed from a fluorine-containing precursor and/or hydrogen (H2) is described, where the plasma effluents react with exposed surfaces and selectively remove tungsten while very slowly removing other exposed materials.
Patent
Highly selective doped oxide removal method
TL;DR: In this article, a method of etching doped silicon oxide on patterned heterogeneous structures is described and includes a gas phase etch using partial remote plasma excitation, which excites a fluorine-containing precursor and the plasma effluents created are flowed into a substrate processing region.
