Test Wafers

Pure Wafer produces test grade wafers in all diameters from 50.8mm to 450mm with the use of our two production facilities located in the Western United States. Test grade wafers are high quality but have less stringent properties than prime grade wafers, usually failing for one or more of the Semiconductor Equipment and Materials International (SEMI) standards. Test grade wafers are often used in applications that require a large quantity of wafers for equipment and fabrication testing.
