WebWafers are round discs with – industry standard – a diameter of 300 millimeters. The light changes the chemistry of the resist layer, so that the exposed parts can later be removed by means of etching. The structure of the conductor paths on the wafer is exposed and the remaining photoresist layer is removed.
