Process monitor for wafer thinning

Abstract:

A system and method for thinning an integrated circuit (IC) wafer. The system includes a support structure to hold the IC wafer and a mechanism to operate on the IC wafer. The support structure includes one or more inductive coils configured to transmit a power signal to the IC wafer and receive a feedback signal from the IC wafer. The system further includes a process controller to control the operation based at least in part on the feedback signal received from the IC wafer.
