Contact hole patterning
WebJul 16, 1998 · For fabrications of 130nm design rule devices, sub-l50nm contact hole patterns are required. However, resolution of contact hole pattern by KrF lithography is limited to 200nm. So Electron Beam(EB) lithography and Phase Shift Mask(PSM) technology have been used and investigated for sub-l50nm contact hole patterning. WebJan 16, 2012 · Sublithographic patterning using Directed Self-Assembly (DSA) is demonstrated for practical circuits with non-periodic features. The DSA of irregularly distributed contact holes is guided by small topographical templates patterned by immersion 193 nm optical lithography. We experimentally demonstrate flexible and …
