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.
