发明名称 Method for wafer back-grinding control
摘要 A method of reducing manufacturing defects of semiconductor wafers during a back-grinding process. The method includes receiving a semiconductor wafer on a chuck table, wherein said chuck table has a surface upon which a front side of the wafer is placed, and wherein said chuck table has one or more holes in surface and one or more sensors placed in said one or more holes. The method further includes grinding at least a portion of a back side of the semiconductor wafer. The method further includes monitoring a parameter, while grinding, measured by the one or more sensors and adjusting the grinding based at least on the monitored parameter.
