SC779: Polarization for Lithographers
The advent of ultra high numerical aperture (NA) systems enabled by immersion lithography has quickly brought polarization toward the top of the lithographer's list of concerns. A high index liquid between the resist and the last lens element allows better resolution by enabling larger angles of incidence, and thus more diffraction energy to couple into the resist. However various polarizing effects can become severe with these large angles of incidence. Most notably contrast from the TM component drops to near or below zero. Thus, the engineering of polarization states is becoming a necessary resolution enhancement technique. Consequently, understanding and controlling polarization throughout all components of the optical system become critical. This course provides the lithographer a basic knowledge of polarization and its application to high-NA imaging. After an introduction to the concept of polarization and the various ways it can be represented, both the benefits and limitations of its application to lithography are discussed. The polarizing effects of each component of the optical system are addressed, offering an understanding of their ultimate impact on imaging.
