Silicon Wafer Manufacturing Process

Silicon Wafer Manufacturing Process

Most prime grade silicon wafers go through 2-3 stages of polishing, using progressively finer slurries or polishing compounds. The majority of the time, wafers are polished on the front side only, excluding 300mm wafers which are double side polished .
