Lithography depth of focus

Web18 mrt. 2015 · The mask plays a significant role as an active optical element in lithography, for both EUV and immersion lithography. Mask-induced and feature dependent shifts of the best focus position and other aberration-like effects were reported both for deep ultraviolet (DUV) immersion and for EUV lithography. Web3.1. The Contact Aligner (Front, back-IR and back-Optical) The contact aligner is a tool that performs alignment and exposure of wafers. The features on the contact aligner mask are the same size as they should be on the wafer (i.e. 1x magnification). Pattern transfer takes place by printing, i.e. by placing the mask in direct contact with the ...
