Extreme Ultraviolet Photoresists : Film Quantum Yields And Ler Of Thin Film Resists, Craig D. Higgins
Legacy Theses & Dissertations (2009 - 2024)
Extreme ultraviolet (EUV) is the leading candidate for a commercially viable solution for next generation lithography. The development of EUV chemically amplified photoresists and processes are critical to the future lithographic requirements of the microelectronics industry. To meet the necessary requirements for both integrated circuit (IC) specifications and cost, the resolution, line-edge roughness (LER) and sensitivity all need to be reduced. Unfortunately, a fundamental trade-off has been observed between these three crucial elements. We have predicted that the best way to obtain the required resolution, line-edge roughness and sensitivity (RLS) is to create more acid molecules per photon absorbed. This …

Legacy Theses & Dissertations (2009 - 2024)
Extreme ultraviolet lithography (EUV) is a promising candidate for next generation lithography. Although EUV has great potential there are still many challenges that must be solved before the technology can be implemented in the high volume manufacturing of semiconductor devices. The lithographic performance of EUV photoresists is one aspect that requires improvement. Particularly, EUV resists need simultaneous improvements in three properties: resolution, line-edge-roughness and sensitivity. The incorporation of acid amplifiers (AAs) in resists is one method to improve all three properties.
