Products – Siltronic / perfect silicon solutions

Monocrystalline silicon is a very brittle material with a high risk of breaking. Special care is consequently needed in order to avoid mechanical damages on the edge of the wafer. The unrounded silicon wafer is mounted onto a grinding chuck and a profile rounding

Wafer Thinning - Silicon Valley Microelectronics

Wafer lapping is a global planarization process that improves wafer flatness by removing surface damage, often from backside grinding. It is most common on silicon wafers, although certain applications require gallium arsenide (GaAs) and indium phosphide (InP) wafers to undergo this process as well. Lapping takes place between two counter ...

Silicon Wafer Production - MKS Inst

The elemental silicon used in semiconductor device manufacture is produced from high purity quartz and quartzite sands, which contain relatively few

Silicon recovery from metallurgical-grade silicon refined ...

MG-Si refining slag obtained by this process accounted for 10% of global silicon production, with more than 15% MG-Si trapped in the slag (Wu et al., 2014). Since the annual global MG-Si production exceeds 3 million tons ( Huang et al., 2017 ), this means that approximately 400,000 tons of MG-Si refining slag is obtained as a by-product ...
