Advanced Lithography and the Semiconductor Industry Roadmap

Semiconductor devices are expected to continue their historic trend of diminishing size for at least several more device generations. Patterning at 65-, 45-, 32-nm and beyond is being enabled by new developments in optical lithography. “Conventional” 193-nm projection lithography will be replaced by liquid immersion lithography, double patterning processes, sophisticated mask design, and other technologies. Alternative lithographies, such as extreme ultraviolet (EUV) projection, electron-beam direct write, and nanoimprint, must compete with enhanced optical lithography in terms of cost, yield, and throughput. This talk will discuss the various aspects of sub-65 nm optical lithography, and place them in the broader context of the semiconductor industry roadmap. Topics will include prospects of high-index liquid immersion lithography, the applicability of double patterning, resist limitations, as well as new lithographic concepts. 

 Mordechai Rothschild

Mordechai Rothschild is Leader of the Submicrometer Technology Group at MIT Lincoln Laboratory. He has led a number of programs in lithography, microfabrication, and photochemistry, including the development of 193-nm optical lithography, which is the lithography used to fabricate most advanced semiconductor devices; and the development of liquid immersion lithography, which is expected to be the leading lithography in the next few years. He is a member of the U.S. Lithography Technical Working Group, which participates in formulating the International Technology Roadmap for Semiconductors (ITRS). He holds a B.S. degree in Physics from Bar-Ilan University, Israel, and a Ph.D. in Optics from the University of Rochester.
