ECE 510

Science, Technology, and Applications

Course Director: Kanti Jain
Description: This course provides a comprehensive foundation in the broad field of micro/nanolithography for graduate students in varied research areas. Lithography is the central process technology used in fabrication of a vast array of micro/nano structures required in microelectronic devices, displays, flexible electronics, microelectromechanical systems, and biotechnology. The course covers the science of microlithography, including optical imaging, photochemistry, and materials issues; the extensive technological developments, including state-of-the-art commercial lithography systems; and the innumerable applications of lithography in diverse fields.
Notes: Course Materials: Chapters from several books, numerous journal articles, proceedings of conferences, and industry reports
