Abstract:
1. A mask pattern comprising: a resist pattern; and a gel layer on a surface of the resist pattern having a junction comprising hydrogen bonds between a proton donor polymer and a proton acceptor polymer, wherein the junction of the gel layer comprises: a plurality of regions capable of undergoing hydrogen bonding, wherein the proton donor polymer and the proton acceptor polymer are hydrogen bonded therebetween; and a defect region wherein the proton donor polymer and the proton acceptor polymer are not hydrogen-bonded therebetween so as to form a region lacking hydrogen bonding, between the hydrogen-bonded regions, the defect region of the gel layer forming a loop between the hydrogen bonded regions and the proton donor polymer of the defect region comprises a —COOR group wherein R is a substituted or unsubstituted C wherein the proton donor polymer comprises a first repeat unit comprising a maleic acid monomer unit according to the following formula: wherein R
