    Abstract: The present invention generally comprises a showerhead insulator for electrically isolating a showerhead assembly from a processing chamber wall, a chamber liner assembly for lining a processing chamber, a lower chamber liner for lining an evacuation area of a processing chamber, and a flow equalizer for ensuring a uniform evacuation of a processing chamber. When processing a substrate within an etching chamber, the showerhead needs to be electrically isolated from ground. A showerhead insulator may insulate the showerhead from ground while also preventing plasma from entering the volume that it occupies. A chamber liner may protect the chamber walls from contamination and reduce chamber cleaning. A flow equalizer will permit processing gases to be evenly pulled into the evacuation channel rather than a disproportionate flow into the evacuation channel. A lower liner can aid in uniformly drawing the vacuum and protecting the chamber walls from contamination.

    Abstract translation: 本发明通常包括用于将喷头组件与处理室壁电隔离的喷头绝缘体,用于衬里处理室的腔室衬套组件,用于衬里处理室的抽空区域的下室衬套和用于确保 均匀排出处理室。 当在蚀刻室内处理衬底时,喷头需要与地电隔离。 喷头绝缘体可以将喷头与地面隔离,同时也防止等离子体进入其占据的体积。 腔室衬垫可以保护腔室壁免受污染并减少腔室清洁。 流量均衡器将允许将处理气体均匀地拉入抽空通道,而不是不成比例的流入排气通道。 下层衬垫有助于均匀地抽真空并保护室壁免受污染。
