Abstract
Embodiments of the disclosure include a temperature control assembly for performing a crystal growth process. The temperature control assembly will include one or more temperature distribution units (TDUs) coupled to an end cap of a capsule. Each of the one or more TDUs comprise: an interior component comprising a major surface; a heating element disposed over the major surface of the interior component; a via tube comprising a central opening that is configured to accommodate lead wires, wherein the lead wires are configured to electrically connect the heating element to a power supply which is disposed on a side of the end cap that is opposite to the side on which the via tube is disposed; and a sheath layer covering the interior component, the heating element, and the via tube, wherein the sheath layer is hermetically sealed to the end cap and is configured to isolate the interior component, the heating element, and the via tube from an external environment in which the one or more TDUs are disposed during processing.
