Summary:Process kits, processing chambers, and methods for processing a substrate are provided. The process kit includes an edge ring, an adjustable tuning ring, and an actuating mechanism. The edge ring has a first ring component interfaced with a second ring component that is movable relative to the first ring component to form a gap between the first ring component and the second ring component. The second ring component has an inner thickness that is less than the outer thickness, and at least a portion of an upper surface of the second ring component is inwardly angled towards the ring first component. The adjustable tuning ring has an upper surface that contacts the lower surface of the second ring component. The actuating mechanism is interfaced with the lower surface of the adjustable tuning ring and is configured to actuate the adjustable tuning ring such that the gap between the first ring component and second ring component is varied. The present invention satisfies a continual need for an improved process kit for a substrate processing apparatus. 기판을 프로세싱하기 위한 프로세스 키트들, 프로세싱 챔버들, 및 방법들이 제공된다. 프로세스 키트는 에지 링, 조정가능 튜닝 링, 및 작동 메커니즘을 포함한다. 에지 링은 제1 링 컴포넌트를 갖고, 제1 링 컴포넌트는 제1 링 컴포넌트에 대해 이동가능한 제2 링 컴포넌트와 인터페이싱하여 제1 링 컴포넌트와 제2 링 컴포넌트 사이에 갭을 형성한다. 제2 링 컴포넌트는 외측 두께보다 작은 내측 두께를 갖고, 제2 링 컴포넌트의 상부 표면의 적어도 일부는 제1 링 컴포넌트를 향해 안쪽으로 각이 진다. 조정가능 튜닝 링은 제2 링 컴포넌트의 하부 표면과 접촉하는 상부 표면을 갖는다. 작동 메커니즘은 조정가능 튜닝 링의 하부 표면과 인터페이싱하며, 제1 링 컴포넌트와 제2 링 컴포넌트 사이의 갭이 변화되도록 조정가능 튜닝 링을 작동시키도록 구성된다.
