Zusammenfassung:New lithographic processing methods are provided which are particularly useful in immersion lithography schemes. In one aspect, processes of the invention comprise: applying on a substrate a photoresist composition; exposing the photoresist layer to radiation activating for the photoresist composition; removing a portion but not all of the exposed photoresist layer; and developing the treated photoresist layer to provide a photoresist relief image.
