APPARATUS FOR AND METHOD OF WAFER GRINDING

Abstract(summary):

An apparatus (10) for wafer grinding includes sensors (38) and a spectral analyzer to perform a spectral analysis of light received by the sensors (38) during grinding of a semiconductor wafer (12). Based on the spectral analysis, the grinding process is stopped or the force applied to the semiconductor wafer is modified. This in situ monitoring decreases breakage and overheating of the semiconductor wafer (12).
