Abstract: The present disclosure generally relates to gas inject apparatus for a process chamber for processing of semiconductor substrates. The gas inject apparatus include one or more gas injectors which are configured to be coupled to the process chamber. Each of the gas injectors are configured to receive a process gas and distribute the process gas across one or more gas outlets. The gas injectors include a plurality of pathways, a fin array, and a baffle array. The gas injectors are individually heated. A gas mixture assembly is also utilized to control the concentration of process gases flown into a process volume from each of the gas injectors. The gas mixture assembly enables the concentration as well as the flow rate of the process gases to be controlled.

Abstract: Apparatuses including a height-adjustable edge ring, and methods for use thereof are described herein. In one example, a substrate support assembly includes a height-adjustable edge ring, and the substrate support assembly is located within a process chamber. The substrate support assembly includes an electrostatic chuck, an edge ring positioned on a portion of the electrostatic chuck, and one or more actuators to adjust the height of the edge ring via one or more push pins. The height-adjustable edge ring can be used to compensate for erosion of the edge ring over time. In addition, the height-adjustable edge ring can be removed from the process chamber via a slit valve opening without venting and opening the process chamber. The height-adjustable edge ring can be tilted by the one or more actuators in order to improve azimuthal uniformity at the edge of the substrate.
