发明名称 Auto feedback apparatus for laser marking
摘要 A method of manufacturing integrated circuits includes measuring a reflectivity value of a wafer. An optimum energy level for laser marking the wafer is determined using the reflectivity value. A laser beam having the optimum energy level is then emitted to make laser marks on the wafer.
