Paper Abstract
As semiconductor features shrink in size and pitch, the pattern placement error at photomask, that is, the registration
becomes more important factor to be reduced. Following ITRS roadmap, the registration for sub-45 nm node is required
to be less than 5 nm but this specification still corresponds to the challengeable goal. Among several reasons to induce
registration, here, we have focused on four major registration errors: e-beam positioning error, patterning effect, pellicle
attachment effect, and sampling error of measurement. We quantify and analyze each error with the help of finite
element modeling and by experiment. Based on these results, we present the current status and the goal of each error for
the roadmap of sub-45 nm node.
