Paper Abstract

An electrical test vehicle for fabricating direct self-assembly (DSA) sub-30 nm via interconnects has been fabricated employing a soft mask grapho-epitaxy contact-hole shrink. The generation of the resist pre-pattern was carried out using 193i lithography on three different stacks and the BCP assembly was evaluated with and without template affinity control on the resist pre-pattern. After DSA shrink, the holes were transferred in a 100 nm oxide for standard Tungsten metallization for electrical characterization.
