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

Effects of Machining Fluid on Electric Discharge …

Recently, ingots of silicon carbide have been adapted to be sliced by the wire-cut electrical discharge machining. Fast slicing, and the reduction in the loss are important for slicing of the wafer. In this paper, characteristic features of the electric discharge machining in the ion-exchange water and the fluorine-based fluid were compared for these improvement.

Silicon - High Precision Machining - Insaco

Silicon is well known as a key component of electronic devices and also of solar cells. For these appliions, the silicon must be purified from its initial form. Silicon is certainly a readily available raw material since it is actually the third most abundant element on Earth after only iron and oxygen, and is handy to isolate from common sand by reduction with coke in the presence of iron.
