Paper Abstract

A revolutionary CD error detection tool, the linewidth bias measurement (LBM), has been developed by the PDC group of Applied Material to solve the localized CD error detection issue for 0.18 micrometer and below design rule reticles. In this paper, we discussed, characterized and tested the LBM tool on both designed testers and real production reticles. Several potential applications have been demonstrated and discussed.
