The Czochralski process is the only process used commercially for production of monocrystalline silicon for semiconductor and solar cell applications. The process has traditionally been controlled using nested single-loop PID controllers. Advanced model-based control will require the ability to...

The Czochralski process is the only method used commercially for production of monocrystalline silicon for semiconductor and solar cell applications. This paper explores the use of mathematical modeling as an aid in estimation of system state variables in the standard Czochralski process. A state...

The Czochralski (CZ) crystallization process is used to produce monocrystalline silicon, which is used in solar cells and electronics. The temperature of the crucible containing the molten silicon must be tightly controlled to achieve high silicon quality. SINTEF Materials and Chemistry in Trondheim...

The Czochralski (CZ) crystallization process is used to produce monocrystalline silicon, which is used in solar cells and electronics. This paper considers adaptive system identification of the dynamics from the triode for alternating current (TRIAC) to the actual (measured) heating element power at...
