GROWING APPARATUS FOR SINGLE CRYSTAL

摘要

PURPOSE: A single crystal growth apparatus is provided to prevent contamination of a thermal insulator by arranging an inner furnace within an outer furnace and growing a single crystal ingot. CONSTITUTION: An outer furnace (100) has an internal space. An inner furnace (200) is arranged inside of the outer furnace. The inner furnace has an internal space accommodating a raw material (A). A thermal insulator (600) is arranged in the outer side of the outer furnace. A seed crystal holder (400) is arranged in an upper side of the furnace and fixes a seed crystal (300).
