Abstract: Embodiments described herein generally related to a substrate processing apparatus. In one embodiment, a process kit for a substrate processing chamber disclosed herein. The process kit includes a ring having a first ring component and a second ring component, a sliding ring, and an actuating mechanism. The first ring component is interfaced with the second ring component such that the second ring component is movable relative to the first ring component forming a gap therebetween. The sliding ring is positioned beneath the ring and contacts a bottom surface of the second ring component. A top surface of the sliding ring contacts the second ring component. The actuating mechanism is interfaced with the bottom surface of the sliding ring. The actuating mechanism is configured to actuate the sliding ring such that the gap between the first ring component and the second ring component varies.
