Silicon Ingot Production - MicroChemicals
www.microchemicals.coman RF coil melts a small region of the polysilicon which, after cooling down, forms mono-crystalline silicon with the crystallographic orientation of the seed crystal (e.g. <100>, <110> or <111> as defi ned in section 1.4). The Radio-frequency (RF) coil and the melted zone move along the entire ingot. Since most impurities
