Description

Technical Field

[0001] This utility model relates to the field of single crystal growth furnace technology, and more specifically, to an indium phosphide single crystal growth furnace. Background Technology

[0002] Indium phosphide is an inorganic compound, a silvery-gray single crystal, extremely slightly soluble in inorganic acids, and primarily used as a semiconductor material in fiber optic communication technology. A single-crystal silicon growth furnace is a manufacturing device that produces single-crystal silicon using the Czochralski method. It mainly consists of three parts: the main unit, the heating power supply, and the computer control system.

[0003] A search revealed an indium phosphide high-pressure single crystal growth furnace with publication number CN213013163U. This furnace includes a furnace body, a cooling system, a heating system, and a constant pressure system. The furnace body comprises a cylinder, an upper end cover at the top, a lower end cover at the bottom, and a mounting frame on the cylinder. The constant pressure system includes an air inlet on the lower end cover and an air outlet on the upper end cover. The air inlet penetrates the lower end cover and connects to the interior of the cylinder. The air outlet includes an air outlet on the upper end cover, a three-way pipe with its first end connected to the air outlet, a pressure relief valve connected to the second end of the three-way pipe, and an exhaust pipe connected to the third end of the three-way pipe. The exhaust pipe is connected to external industrial waste gas recovery equipment. The pressure relief valve's relief port is connected to the outside air. The air outlet penetrates the upper end cover and connects to the interior of the cylinder. This furnace can improve the single crystal yield of indium phosphide and ensure the quality of indium phosphide single crystal growth.

[0004] For common indium phosphide single crystal growth furnaces, the external location does not have an isolation and protection structure. If workers in the production workshop accidentally touch it, it will directly affect the growth of indium phosphide single crystals by the Czochralski method, thereby reducing product quality. Therefore, we propose an indium phosphide single crystal growth furnace to solve the above-mentioned problems. Utility Model Content
