APPARATUS AND METHOD FOR MEASURING MELT LEVEL OF SILICON SINGLE CRYSTAL GROWER

摘要

PURPOSE: An apparatus and method for measuring the melt level of a single crystal growing device are provided to produce an ingot with high quality by precisely controlling a melt gap. CONSTITUTION: A contact bar (710) moves from a referent position to melt and is in contact with the melt. A moving unit (720) is connected to the contact bar and moves the contact bar. An operation unit (730) measures a melt level by calculating the movement distance of the contact bar. A control unit (740) controls the moving unit and the operation unit. A contact sensor (750) senses a contact between the melt and the contact bar. [Reference numerals] (740) Control unit; (750) Contact sensor
