    摘要: A top anti-reflective coating material (TARC) and barrier layer, and the use thereof in lithography processes, is disclosed. The TARC/barrier layer may be especially useful for immersion lithography using water as the imaging medium. The TARC/barrier layer comprises a polymer which comprises at least one silicon-containing moiety and at least one aqueous base soluble moiety. Suitable polymers include polymers having a silsesquioxane (ladder or network) structure, such as polymers containing monomers having the structure: where R1 comprises an aqueous base soluble moiety, and x is from about 1 to about 1.95, more preferably from about 1 to about 1.75.

    摘要: A solution for performing an optical proximity correction (OPC) process on a layout by incorporating a critical dimension (CD) correction is provided. A method may include separating the layout into a first portion and a second portion corresponding to the two exposures; creating a model for calculating a CD correction for a site on the first portion, the model corresponding to a topography change on the site due to the double exposures; implementing an OPC iteration for the fragment based on the model to generate an OPC solution for the first portion; and combining the OPC solution for the first portion with an OPC solution for the second portion to generate an OPC solution for the layout to generate a mask for fabricating a structure using the layout.
