Abstract

In this paper, we investigate an electric-field assisted assembly approach to create dense arrays of contact hole patterns with complex feature geometries. This hybrid strategy uses a spatially varying dielectrophoretic (DEP) force created by lithographically defined guiding features to assemble dense arrays of nanoparticles within the features, thereby replicating features within the starting pattern. For close-packed particle arrays, the half- and full-pitch of the contact hole array is defined by the starting nanoparticle core and shell diameter.
