  • Heater assembly for crystal growth apparatus
    Patent number: 9303331
    Abstract: Systems and methods are provided to promote uniform thermal environment to feedstock material (e.g., silicon) in a crucible of a crystal growth apparatus are provided herein. More specifically, a heating system may be arranged in the crystal growth apparatus so as to include at least a first and second heating element which are configured to distribute heat axisymmetrically to the feedstock material and the second heating element that is configured to distribute heat symmetrically to the feedstock material to thereby provide uniform heat distribution to the feedstock material in the crucible to allow for increased consistency in crystal ingot quality.
    Type: Grant
    Filed: June 6, 2012
    Date of Patent: April 5, 2016
    Inventors: Carl Chartier, Parthasarathy Santhanaraghavan, Andriy Andrukhiv, Dave Lackey, Bhuvaragasamy G. Ravi
