    摘要: Compositions and methods are provided that can reduce reflection of exposing radiation from a substrate back into an overcoated photoresist layer and/or function as a planarizing or via-fill layer. Preferred coating composition and methods of the invention can provide enhanced resolution of a patterned overcoated photoresist layer and include use of low activation temperature thermal acid generators as well as multiple thermal treatments to process a layer of the underlying coating composition.

    摘要: Compositions (particularly antireflective coating compositions or “ARCs”) are provided that can reduce reflection of exposing radiation from a substrate back into an overcoated photoresist layer and/or function as a planarizing or via-fill layer. More particularly, the invention relates to organic coating compositions, particularly antireflective coating compositions, that contain a polyester resin component that contains repeat units that comprise phenolic and/or hydroxyalkylcyanurate groups.

    摘要: A method of forming a pattern comprises diffusing an acid formed by irradiating a portion of a photosensitive layer, into an underlayer comprising an acid sensitive copolymer having acid decomposable groups and attachment groups covalently bonded to the surface of the substrate and/or forming an interpolymer crosslink. Diffusing comprises heating the underlayer and photosensitive layer. The acid sensitive group reacts with the diffused acid to form a polar region on the underlayer, with the shape of the pattern. The photosensitive layer is removed, forming a self-assembling layer comprising a block copolymer having a first block with an affinity for the polar region, and a second block having less affinity for the polar region. The first block forms a domain aligned to the polar region, and the second block forms another domain aligned to the first. Removing either domain exposes a portion of the underlayer.
