What is a Silicon Wafer? Silicon Valley Microelectronics

Ingot GrowthSlicingCleaningPolishingPackagingTo grow a ingot, the first step is to heat the silicon to 1420°C, above the melting point of silicon. Once the polycrystalline and dopant combination has been liquified, a single silicon crystal, the seed, is positioned on top of the melt, barely touching the surface. The seed has the same crystal orientation required in the finished ingot. To achieve doping uniformity, the seed crystal and the crucible of molten silicon rotate in opposite direction在svmi上查看更多信息
