  • Methods and Systems For Controlling SiIicon Rod Temperature
    Publication number: 20120322175
    Abstract: Systems and methods are provided for controlling silicon rod temperature. In one example, a method of controlling a surface temperature of at least one silicon rod in a chemical vapor deposition (CVD) reactor during a CVD process is presented. The method includes determining an electrical resistance of the at least one silicon rod, comparing the resistance to a set point to determine a difference, and controlling a power supply to control a power output coupled to the at least one silicon rod to minimize an absolute value of the difference.
