Paper Abstract

With increased demand for reliable and automated semiconductor wafer inspection, machine vision techniques are much needed for defect extraction and identification and pre- and post-processing operations. The wavelet-based approach is emphasized in this paper for its capability to meet different needs in wafer inspection. The algorithms involved are illustrated by using a number of wafer inspection images.
