Abstract

High-precision leveling for polymer pen lithography is demonstrated by N.-J. Cho, S.-J. Cho, and co-workers with a 0.001° slope of feature edge-length variation over 1 cm-wide tip arrays. This approach, described on page 4526, employs a multi-point force sensing structure in order to take into account the magnitude and direction of the total applied force of the tip array.
