    摘要: The present invention provides polymers that are useful in negative resist compositions. Polymers of the present invention comprise (1) a first monomer having a polar functional group; (2) a second monomer; and optionally, (3) a third monomer that imparts at least one characteristic selected from crosslinkable functionality, etch resistance, and solubility modulation. The first monomer provides an acid catalyzed polarity switch upon elimination of the polar functional group, whereas, the second monomer provides aqueous dissolution. The polymers of the present invention may be incorporated into negative resist compositions, which may also include photoacid generators, crosslinking agents, basic compounds, solvents, dissolution accelerators, photobase generators, latent basic compounds, surfactants, adhesion promoters, and anti-foaming agents.

    摘要: Compositions, a method, and a photopatternable blend. The compositions include a blend of a first and a second polymer. The first polymer is a substituted silsesquioxane copolymer. The second polymer is a substituted silsesquioxane polymer. The second polymer is configured to undergo chemical crosslinking with the first polymer, the second polymer, or a combination thereof, upon exposure to light, thermal energy, or a combination thereof. The compositions include a photosensitive acid generator. The method includes forming a film. The film is patternwise imaged, and at least one region is exposed to radiation. After the imaging, the film is baked, wherein at least one exposed region is rendered substantially soluble. After the baking, the film is developed, wherein a relief pattern remains. The relief pattern is exposed to radiation. The relief pattern is baked. The relief pattern is cured. A chemically amplified positive-tone photopatternable blend is also described.
