Abstract: A shaft member includes a cylindrical body formed from a ceramic material and having a drive segment, a frustoconical segment, and an end key segment. The drive segment extends about a rotation axis, the frustoconical segment is offset from the drive segment along the rotation axis, and the end key segment extends axially from the frustoconical segment and is axially separated from the drive segment by the frustoconical segment of the shaft member. The end key segment has a first circumferential facet and a second circumferential facet circumferentially opposite the first circumferential facet to fix the shaft member in rotation about the rotation axis relative to a support member seated when the end key segment is slidably received within an end key socket defined within the support member. Process kits, semiconductor processing systems, and methods of making semiconductor processing systems are also described.

Abstract: A lift pin actuator includes a castellated annulus, a first arm, a second arm, and a pin pad. The annulus arranged along a rotation axis and has a first merlon and a second merlon circumferentially separated by a crenel. The first arm is connected to the first merlon and extends outward from the annulus, the second arm is connected to the second merlon and extends outward from the annulus, and the second arm is circumferentially spaced from the first arm by a radial gap. The pin pad is connected to the annulus by the first arm and the second arm, is radially spaced from the annulus by the radial gap, and radially overlaps the crenel to nest a support member within the lift pin actuator during translation of the lift pin actuator along the rotation axis relative to the support member. Process kits, semiconductor processing systems, methods of making lift pin actuators and related material layer deposition methods are also described.
