Silicon crystal growth in vacuum - NASA/ADS

The most developed process for silicon crystal growth is the Czochralski (CZ) method which was in production for over two decades. In an effort to reduce cost of single crystal silicon for photovoltaic appliions, a directional solidifiion technique, Heat Exchanger Method (HEM), was adapted. Materials used in HEM and CZ furnaces are quite similar (heaters, crucibles, insulation, etc.). To

Mechanism and modeling of silicon carbide formation …

This paper proposes a mechanism of carbon species formation and transport in the gas phase and silicon carbide particle formation and engulfment in the liquid phase. A numerical model considering various forces acting on silicon carbide particles is developed to quantify particle transport and particle engulfment. Numerical simulations are conducted to study fluid flow and temperature

Inclusions of carbon in ingots of silicon carbide grown …

The problem of the appearance of carbon inclusions in single-crystal silicon carbide ingots grown by the modified Lely method (the so-called graphitization of the ingot) is analyzed. It is shown that the process of graphitization of the ingot is not related to a deficit of silicon in the growth cell; in contrast, it is excess of silicon at the growth surface that inhibits the ingot growth rate
