  • Publication number: 20110147983
    Abstract: A method of forming a layered structure comprising a domain pattern of a self-assembled material comprises: disposing on a substrate a photoresist layer comprising a non-crosslinking photoresist; optionally baking the photoresist layer; pattern-wise exposing the photoresist layer to first radiation; optionally baking the exposed photoresist layer; and developing the exposed photoresist layer with a non-alkaline developer to form a negative-tone patterned photoresist layer comprising non-crosslinked developed photoresist; wherein the developed photoresist is not soluble in a given organic solvent suitable for casting a given material capable of self-assembly, and the developed photoresist is soluble in an aqueous alkaline developer and/or a second organic solvent. A solution comprising the given material capable of self-assembly dissolved in the given organic solvent is casted on the patterned photoresist layer, and the given organic solvent is removed.

  • Patent number: 7855045
    Abstract: A topcoat material for applying on top of a photoresist material is disclosed. The topcoat material comprises at least one solvent and a polymer which has a dissolution rate of at least 3000 ?/second in aqueous alkaline developer. The polymer contains a hexafluoroalcohol monomer unit comprising one of the following two structures: wherein n is an integer. The topcoat material may be used in lithography processes, wherein the topcoat material is applied on a photoresist layer. The topcoat material is preferably insoluble in water, and is therefore particularly useful in immersion lithography techniques using water as the imaging medium.
