Directed self-assembly (DSA) technology has already demonstrated its capability for isolated and grouped contact/via pattern for 1D gridded design. If we reverse the resist tune, this technique can also be used to implement the cut printing. However, for this purpose, we need to redistribute the cuts by extending the real wires to form the desired cut distribution for template mask making. Based on this assumption, we propose an algorithm to redistribute the original cuts such that they form groups of non-conflict DSA templates. Expérimental results demonstrate that our method can effectively redistribute the cuts and improve the layout manufacturability.
