The Manufacturing Process of Silicon Wafers. The production of silicon wafers is a multi-step process that begins with the extraction of raw silicon from quartz. Silicon (Si) is the second most abundant element on Earth, but it is not found in its pure form. Instead, it is typically found in the form of silicon dioxide (SiO2) or quartz.
