The second edition of this volume is written not only as an introduction to the science
and technology of microlithography, but also as a reference for those who with more
experience so that they may obtain a wider knowledge and a deeper understanding of
the field. The purpose of this update remains consistent with the first edition published in
1998 and edited by Dr. James R. Sheats and Dr. Bruce W. Smith. New advances in lithography
have required that we update the coverage of microlithography systems and
approaches, as well as resist materials, processes, and metrology techniques.
