Paper Abstract

We report here the development of SMART SET', an expert system designed to complement the GCA DSW Wafer Stepperg, such that closed loop feedback for stepper set-up and calibration is realized. In particular, SMART SET' enables the user to monitor and optimize overlay and utilization performance. Measurements are obtained directly from the automated local alignment and history file systems of the stepper. An analysis package which embodies the expertise of stepper applications engineers provides rapid feedback of the system corrections required to sustain optimum stepper performance.
