Abstract
The dispersive method of white-light interferometry is proper for in-line 3-D inspection of dielectric thin-film thickness to be used in the semiconductor and flat-panel display industry. This research is the measurement application of CMP patterned wafer. The results describe 3-D and 2-D profile of the step height during polishing time.
