    Abstract: A method of etching exposed patterned heterogeneous structures is described and includes a remote plasma etch formed from a reactive precursor. The plasma power is pulsed rather than left on continuously. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents selectively remove one material faster than another. The etch selectivity results from the pulsing of the plasma power to the remote plasma region, which has been found to suppress the number of ionically-charged species that reach the substrate. The etch selectivity may also result from the presence of an ion suppression element positioned between a portion of the remote plasma and the substrate processing region.

    Abstract translation: 描述了蚀刻暴露的图案化异质结构的方法,并且包括由反应性前体形成的远程等离子体蚀刻。 等离子体功率是脉冲的,而不是连续地保持。 来自远程等离子体的等离子体流出物流入衬底处理区域,其中等离子体流出物选择性地比另一种更快地去除一种材料。 蚀刻选择性是由等离子体功率脉冲到远程等离子体区域而产生的,这已经被发现抑制了到达衬底的离子充电物质的数量。 蚀刻选择性也可能由位于远程等离子体的一部分与基板处理区域之间的离子抑制元件的存在引起。

    Abstract: A test device for testing an electrical property of a chamber component, such as a ceramic ring, includes an outer conductor and an inner conductor disposed within and electrically isolated from the outer conductor. The outer conductor has a base, a top, and an interior sidewall disposed between the base and the top. The inner conductor has a top portion having a first diameter and a bottom portion having a second diameter, in which the second diameter is greater than the first diameter. A sample area is defined between the base of the outer conductor and the bottom portion of the inner conductor, and is configured to receive a chamber component. The electrical property of the chamber component is measurable based on application of a signal to at least one of the outer conductor or the inner conductor.
