The present work presents an investigation of the characteristics of a broad band capability photoresist in terms of photo-active compound (PAC) bleachability and process performances. The difference in performance on exposure to 436 and 365 nm wavelengths of a commercially available photoresist, Olin Hunt H1PR-6512, has been evaluated as a function of some typical lithographic parameters by using FT-IR spectroscopy and actinometry. This analysis contributed to the development of a submicron I-line process, which in conclusion is shown in a production environment application.
