Manufacturer Equipment Of Silicon Wafers From Sand

Silicon Wafer Manufacturing

2017-10-5  Firstly, a flawless precious stone ought to get created from silicon. It must be submerged gradually into a vessel with liquid sand. A while later, the ingot (chamber molded unadulterated silicon) get precisely pulled back. The ingot is then meagerly cut, using a precious stone saw and the cut arranged, concurring the thickness of every wafer.
