Abstract:

An electrode assembly for a plasma reaction chamber used in semiconductor substrate processing. The assembly includes an upper showerhead electrode which is mechanically attached to a backing plate by a series of spaced apart cam locks. A guard ring surrounds the backing plate and is movable to positions at which openings in the guard ring align with openings in the backing plate so that the cam locks can be rotated with a tool to release locking pins extending from the upper face of the electrode.

Abstract(Chinese):

用于等离子体反应室的电极组件，用于半导体衬底处理。该组件包括上部喷头电极，其通过一系列间隔开的凸轮锁定机械地附接到背板。保护环围绕背板并且可移动到保护环中的开口与背板中的开口对准的位置，使得凸轮锁可以用工具旋转以释放从电极的上表面延伸的锁定销。
