Paper Abstract

In this paper, we will describe the principle and the design concerns with and without PFOS of TARC materials, and then make a comparison of TARC and organic bottom anti-reflective coating (BARC) which are both anti-reflective coating materials. In our discussions, we will sort the TARC applications, and then discuss the behavior of post-exposure bake (PEB) delay with and without TARC process. After that, we will discuss the material issues which we are faced of Non-PFOS TARCs, such as material being frozen during shipping process, coating performance etc. Then, we will demonstrate the Litho performances and defect results of actual Non-PFOS TARC materials. Finally, we will summarize the evaluation results of Non-PFOS TARC materials.
