Paper Numbering: Proceedings of SPIE follow an e-First publication model, with papers published first online and then in print. Papers are published as they are submitted and meet publication criteria. A unique citation identifier (CID) number is assigned to each article at the time of the first publication. Utilization of CIDs allows articles to be fully citable as soon as they are published online, and connects the same identifier to all online, print, and electronic versions of the publication. SPIE uses a six-digit CID article numbering system in which:
The CID Number appears on each page of the manuscript. The complete citation is used on the first page, and an abbreviated version on subsequent pages. AuthorsNumbers in the index correspond to the last two digits of the six-digit citation identifier (CID) article numbering system used in Proceedings of SPIE. The first four digits reflect the volume number. Base 36 numbering is employed for the last two digits and indicates the order of articles within the volume. Numbers start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B...0Z, followed by 10-1Z, 20-2Z, etc. Altamirano-Sánchez, E., 0C Argoud, M., 0D Arnold, John, 0A, 0F Arnold, Michael S., 0T Azuma, T., 0S Barnola, S., 0B, 0D Beique, Genevieve, 0A, 0F Biolsi, Peter, 0G Boemmels, J., 0W Boettcher, Monika, 0V Bos, S., 0D Braithwaite, N.

IntroductionThis proceedings volume features accepted papers from the SPIE Conference on Advanced Etch Technology for Nanopatterning IV (The SPIE Etch Conference) held as part of the International Symposium on Advanced Lithography, 22–26 February 2015 in San Jose, California. These proceedings papers cover the latest advances in the wide field of etch and nanopatterning technology and offer a glimpse of the state of the art of this important field of semiconductor technology. This year’s conference continued the fine tradition of wide international representation and attracted many researcher from related fields. For the first time, our conference lasted two full days and was divided into eight sessions, all of which continued to garner tremendous interest among conference attendees.
This year, the conference hosted two well-attended joint sessions on Patterning Materials and Etch as well as Materials and Etch in Emerging Technologies with the Advances in Patterning Materials and Processes Conference. The Overview Session, where some of the most important fundamental issues being faced in the world of nanopatterning and etch were discussed, drew very big crowds. We hope that this proceedings volume will prove valuable to the many patterning scientists and engineers working in the fast-moving semiconductor industry. We also hope that it will serve as a useful reference for those who are interested in nanofabrication, micro- and nano-fluidics, micro- and nanophotonics, Micro-Electro-Mechanical Systems (MEMS), BioMEMS, organic electronics, advanced packaging, as well as bio-chips. We thank the authors, particularly the invited speakers, for their valuable contributions to this conference and this proceedings volume. The SPIE Etch Conference is highly regarded among the worldwide patterning community due to the high quality of presentations and proceedings papers. We also thank members of the organizing committee for their dedication and hard work to ensure the high quality of this conference. We are also grateful to LAM Research Corporation for their generous financial support. Finally, we extend our sincere thanks to the SPIE staff for their tireless efforts and their meticulous organizational skills in assembling and publishing this proceedings volume and helping make this year’s SPIE Etch Conference a success.
