Paper Abstract
Image placement (IP) error of a 1x stencil mask is a concern for proximity electron beam lithography (PEL) when considering its application in the 65 and 45-nm nodes. According to our preliminary overlay budget for the 65-nm node, the global IP over the mask and the local IP within each membrane should be kept less than 10 and 7 nm, respectively to fulfill the total overlay accuracy of 23 nm. In this paper, we demonstrate the mask structure and the data processing method that enables the mask to be fully compatible with the local IP requirement in those technology nodes.
