    摘要: Processing defects arising during processing of a semiconductor wafer prior to back-grinding are reduced with systems and methods of sensor placement. One or more holes are bored into a chuck table for receiving semiconductor wafers, or a support table next to the chuck table. One or more sensors are disposed in the holes for monitoring parameters during a pre-back-grinding (PBG) process. A control box converts a set of signals received from the sensors. A computer-implemented process control tool receives the converted set of signals from the control box and determines whether the PBG process will continue.

    摘要: In a system or method for controlling wafer back-grinding, a chuck table has a surface for supporting a semiconductor wafer during a back-grinding process, one or more holes in the surface, and one or more sensors disposed in the one or more holes for monitoring a parameter during back-grinding. A computer-implemented process control tool is coupled to receive one or mote outputs from the one or more sensors and control the back-grinding process based on the received one or more outputs.

    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.
