AMPULE TO REDUCE STRESS BETWEEN THE AMPULE AND SINGLE CRYSTAL AND SINGLE CRYSTAL GROWING APPARATUS HAVING THE SAME

摘要

PURPOSE: A single crystal growing ampulse and a single crystal growing apparatus including the same are provided to improve the quality of grown single crystal ingot by minimizing stress between the inner side of an ampule body and a single crystal sample. CONSTITUTION: An ampule body(2) has a non-parallel shape with regard to a single crystal growing direction. The diameter of the lateral sides(4) of the ampule body gradually increases from the lower side(3) in the single crystal growing direction.
