Legacy Theses & Dissertations (2009 - 2024)
As extreme ultraviolet lithography (EUVL) prepares to be incorporated into high volume manufacturing, many challenges must be addressed. Among these challenges, a need for photoresist improvement exists. The work described here will look into some of the problems and challenges facing EUV resists, in particular out-of-band (OOB) wavelengths of light and their interaction with photoresists. Studies have been completed on the effect of out-of-band light on photoresists [1]-[3]. It is imperative that solutions to suppress the deep ultraviolet (DUV) OOB light be incorporated into next generation EUV production tools due to concerns of decreased performance of lithography, and an increase …
