Lithography patterning

Multiple patterning (or multi-patterning) is a class of technologies for manufacturing integrated circuits (ICs), developed for photolithography to enhance the feature density. It is expected to be necessary for the 10 nm and 7 nm node semiconductor processes and beyond. The premise is that a single lithographic exposure may not be enough to provide sufficient resolution. Hence additional exposures would be needed, or else positioning patterns using etched feature sidewa… Web1 dag geleden · Brewer Science, Inc., a global leader in developing and manufacturing next-generation materials for the microelectronics and optoelectronics industries, will present “New Developments in Underlayers and Their Role in Advancing EUV Lithography” at Critical Materials Council (CMC) Conference.
