摘要：Apparatus and method for monitoring wafer charges are propod. A
conductive pin, a conductive spring and a conductive line are configured in ries to
作大connect the backside surface of the wafer and the sample conductor so that the backside
油豆皮凉拌的做法surface of the wafer and the surface of the sample conductor have identical charge density. Hence, by using a static electricity nsor positioned clo to the surface of the sample conductor, the charges on the wafer may be monitored. Note that the charges appeared on the frontside surface of the wafer induces charges on the backside surface of the wafer. The sample conductor is a sheet conductor and properly insulated from the surrounding environment. As usual, the sample conductor and the static electricity nsor are positioned outside the chamber where the wafer is placed and procesd, so as to simplify the apparatus inside the chamber and reduce the contamination risk.两位数乘两位数
