摘要:

For the first time in the history of the semiconductor industry, we have deviated from the path of Moore’s Law. Getting back on track will require addressing many challenges in materials science. One of the reasons for the delayed progress in resolution improvement is that moving to exposing photoresists in the extreme ultraviolet has proven a daunting task. An alternative approach is to take a cue from optical microscopy, in which resolution enhancement has been achieved by developing techniques that rely on exposure to multiple colors of light. Multicolor lithography is a promising approach for the patterning of negative-tone photoresists with resolution in the tens of nm range using light in the visible or near ultraviolet. This approach is progressing from its original, 2-color schemes to more advanced 3-color schemes that offer substantially better resolution and a greater degree of flexibility in the patterning process.The development of industrially relevant multicolor photoresists will require versatile and highly controllable photochemical approaches. I will discuss our recent progress in this field and new tools that we have developed for the rapid analysis of candidate materials.

 

报告人简介:

John T. Fourkas is the Millard Alexander Professor of Chemistry at the University of Maryland, College Park. He received his BS and MS in Chemistry from Caltech in 1986, and his PhD in Chemistry from Stanford University in 1991. After performing postdoctoral research at the University of Texas, Austin and the Massachusetts Institute of Technology, he joined the faculty of the Department of Chemistry and Biochemistry at Boston College in 1994, and moved to the University of Maryland in 2005. His research interests involve applications of ultrafast, nonlinear optical phenomena in areas such as spectroscopy, imaging, and nanofabrication. He is a Senior Editor for the Journal of Physical Chemistry. He is a Fellow of the OSA, the American Physical Society, and the American Association for the Advancement of Science.
