Abstract:
1. A method for obtaining a patterned structure comprising a fluorine-containing polymeric material comprising the steps of: a) coating a substrate with a layer of fluorine-containing polymeric material; b) coating the substrate from a) with a layer of photoresist material; c) selectively exposing portions of the layer of photoresist material from step b) to radiation forming a first pattern of exposed photoresist material and a second pattern of unexposed photoresist material; d) selectively removing either the first pattern of exposed photoresist material or the second pattern of unexposed photoresist material resulting in a residual pattern in the photoresist layer; and e) transferring the residual pattern of the photoresist layer from step d) to the layer of fluorine-containing polymeric material, such that a patterned structure comprising a fluorine-containing polymeric material is formed.
