Abstract
Mask specification has been playing ever-increasing role for wafer process optimization with tightening design rule. It is very critical to optimize specifications and sampling sizes to ensure quality as well as minimize cost and TPT for high volume manufacturing. In this paper, key parameters for mask specification affecting wafer litho process window will be discussed. Examples of how to derive key mask specification based on the litho process margin will be examined. The mask CD targeting control and plate to plate CD variation reduction strategy will be discussed.
