IMEC to Present at SPIE

IMEC will present 26 papers on their advanced semiconductor lithography research and development at SPIE Advanced Microlithography Conference. The papers cover materials, manufacturing process technology, metrology, inspection, process control, optical microlithography, design for manufacturing, and alternative lithographic processes. SPIE will take place February 23 – 27 in San Jose, California.
