If the photo-reactive areas solidify and the unexposed areas dissolve, this type of photoresist is called negative photoresist as shown in Fig. lactone groups of the ArF photoresist, due to the structural and electronic effects of the lactone groups. The model-based library (MBL) matching technique was applied to measurements of photoresist patterns exposed with a leading-edge ArF immersion lithography tool. Since the degree of shrinkage of the ArF resist depends on the energy and dose of the electron-beam exposure, they should be minimized to suppress the shrinkage.

2.5 Chemical amplification type photoresists for ArF excimer laser lithography To provide greater resolution, the development of lithographic technology shifted away from the KrF excimer laser (248 nm) to the ArF excimer laser (193 nm). Photoresist materials have been developed based on polymers containing photo-reactive groups in their side chains or main chains for KrF and ArF resist systems . High spin speed results in opposite thickness profile as well as random variation in thickness due to thermal effects. However, in practical use of ArF technology, many problems must be solved for the properties of photoresist. Using a commercially available ArF photoresist as a baseline, after the process window, the main focus was on the circularity of the contact hole, which is defined as the CD-ratio between Y- and X-directions as measured by top-down CD-SEM.
