    摘要: The resist compositions having an acid sensitive imaging polymer and a radiation sensitive acid generator component comprising: (i) a first radiation sensitive acid generator selected from the group consisting of dissolution-inhibiting acid generators, and (ii) a second radiation sensitive acid generator selected from the group consisting of unprotected acidic group-functionalized acid generators and acid labile group-protected acidic group-functionalized radiation sensitive acid generators; enables formation of high sensitivity resists suitable for use in EPL, EUV, soft x-ray, and other low energy intensity lithographic imaging applications. The resist compositions may be useful in other lithographic processes as well.

    摘要: A method for reducing critical dimension loss and resist loss dimensions during etching includes providing a dielectric layer having an anti-reflection layer formed thereon and patterning a resist layer on the anti-reflection layer. The resist layer is exposed to an agent including silicon, and the agent is reacted with the resist to form a silylation region on exposed surfaces of the resist layer. The anti-reflection layer is etched by employing the silylation regions as an etch mask wherein the silylation regions have a greater resistance to etching than the antireflection layer and the resist layer.
