Many researchers have studied confinement effect on block copolymer morphology. Although, most of them has focused on symmetric morphology by modifying template surface with neutral brush or selective brush, no one has tried to get anisotropic morphology. Here, I partially modified AAO surface by tilting the template and aluminum deposition. Due to the roughness of alumina layer, I could get stacked lamellar hemisphere structure without neutral brush modification and selective cover. I expect the morphology can be dramastically changed by controlling the roughness, thickness, and area of metal layer. Also, if I use neutral brush or selective brush to modify AAO surface before metal deposition, I expect many interesting asymmentric morphologies can be obtained by anisotropic confinement effect.
