Abstract: According to the disclosed embodiments, a repeatable interface in a crystalline material growth system is achieved through an automated heat exchanger alignment apparatus and method. In one embodiment, a furnace chamber including a bottom wall and side walls that define an interior portion is provided. A crucible is disposed in the interior portion of the furnace chamber and configured to contain a crystalline material growth process. Also, a heat exchanger includes an elongated shaft that extends in a vertical direction and traverses the bottom wall of the furnace chamber, whereby a first end portion of the heat exchanger shaft is coupled to the crucible. Furthermore, an automated lifting device is configured to be actuated to adjust a position of the heat exchanger shaft in the vertical direction, whereby a second end portion of the heat exchanger shaft is coupled to the automated lifting device.
