A novel method for gas flow and impurity control in directional solidification of multi-crystalline silicon

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1155621

In this paper the potential of a specially designed argon gas injector for controlling the gas flow and transport of impurities in directional solidification of multi-crystalline silicon is evaluated. The gas injector which consists of a valve allows one to control the flow direction independently i...

3D dynamic simulation of heat transfer and melt flow in an inductively heated crystallization furnace for mc-silicon with PID temperature control

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1058172

A heat transfer model of a semi-industrial induction furnace has been build, using a 3D finite element model in order to analyze the entire process cycle, based on the heating, melting, solidification and cooling phases of a multi-crystalline square ingot. In the modeling of the entire process, heat...

Dynamic simulation of impurity transport and chemical reactions in a Bridgman furnace for directional solidification of multi-crystalline silicon

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1038250

Numerical results from a dynamic simulation of impurity transport and reactions in a Bridgman furnace for directional solidification of multi-crystalline silicon are presented and compared to experimental results. The simulation includes the calculation of the thermal field, melt and gas flow veloci...

Optimization of silicon crystallization in a Bridgman growth furnace by numerical modeling

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+994232

A heat transfer model of a semi-industrial furnace has been build, using a 3D FEM model in order to analyze the crystallization phase of a multi-crystalline square ingot. In the modeling of the solidification process heat transfer phenomena, such as radiation and conduction in the furnace have been ...
