Abstract: Apparatus for providing gas to a reaction chamber, reactor systems including the apparatus, and methods of using the apparatus and systems are disclosed. The systems and methods as described herein can be used to, for example, provide a mixture of two or more precursors to a reaction chamber with desired flow distribution.

Abstract: A reactor system with stuck lift pin detection. The system includes a reaction chamber, a susceptor for supporting wafers in an interior space of the reaction chamber, and an elevator for raising and lowering the susceptor in the interior space. Further, the system includes a lift pin supported by and extending vertically through the susceptor to travel between an up and a down position with movements of the susceptor by the elevator, and a landing pad is provided in the system for receiving a base of the lift pin when the lift pin is in the down position. Significantly, the system also includes a sensor assembly with a sensor positioned at least partially within the interior space of the reaction chamber. An output signal of the sensor is indicative of whether the lift pin is sticking or seizing during travel through the susceptor.

Abstract: Various embodiments of the present technology may provide a showerhead assembly that includes a showerhead plate having a plurality of through-holes. Each through-hole has a conical-shaped inlet and a conical-shaped outlet. The showerhead plate may include through-holes in a center region having first dimensions and through-holes in an outer region having second dimensions that are different from the first dimensions.
