摘要: A temperature monitor is included inside an ion implanting chamber to constantly monitor the wafer temperature during ion implantation. The measured temperature signal is sent to a central control system through an interface circuit. When an abnormal temperature is detected, the central control system automatically ceases the ion implantation operation and triggers an alarm for operators.
