Lithography resist
WebLithography consists of six basic steps: Wafer Preparation, applying the photoresist coat, softbaking, exposing, post-exposure baking, and development. Notes: Carry the wafers … Web1. INTRODUCTION. EUV lithography was conceived as a potential successor to optical lithography in the late 1980`s. 1 Now, after decades of research and development, the semiconductor industry is poised to use this lithographic technology in high volume manufacturing. Nevertheless, improvements in a few areas, particularly exposure tool …

The major problem associated with the current systems of EUV resist is something known as Reolution-Line edge roughness-Sensitivity (RLS) tradeoff, which is caused due to the … WebThis work presents the fabrication of hollow-core metallic structures with a complete laser interference lithography (LIL) process. A negative photoresist is used as sacrificial layer. It is exposed to the pattern resulting from the interference of two laser beams, which produces a structure of photoresist lines with a period of 600 nm.

Unlike bottom antireflective coatings (BARCs), reflectivity control is no longer the driving mechanism for underlayers. Underlayers are now necessary to support resist performance and enable scaling of the process.
