Self Assembly of Polystyrene Nanospheres

Self assembly of 500 nm polystyrene nanospheres onto optical photoresist. The nanospheres acts like microlenses, exposing the resist and patterning it with a dot structure. After metalisation (in this case sputtered permalloy) the following lift-off leaves the metal structure on the upper pert of the microphoto. In the lower part the original array of self-assembled nanospheres used as microlenses.
