摘要: A reference wafer maintains laser accuracy and calibrates a camera and a laser of a semiconductor equipment. The reference wafer includes a first anti-reflection layer, an adhesive layer, a light absorption layer and a second anti-reflection layer that are stacked over a substrate, a light reflection layer formed over the second anti-reflection layer, and a protection layer formed over the light reflection layer.
