APPARATUS FOR MANUFACTURING SILICON SINGLE CRYSTAL INGOT

摘要

PURPOSE: An apparatus for manufacturing a silicon single crystal ingot is provided to prevent heat dissipation to the outside by arranging a reflecting portion at a circumference of a heating portion. CONSTITUTION: A crucible(10) receives silicon. The crucible is included inside a chamber. A heating portion(20) heats the silicon. An upper insulation portion(32) is arranged on the top of the crucible and shields heat from the heating portion. A reflecting portion(80) is arranged at the outside of the heating portion.
