On behalf of the technical program and organizing committees, we welcome you to the 2015 IEEE International Conference on Integrated Circuit Design and Technology (ICICDT) at IMEC in Leuven, Belgium Integrated circuit (IC) engineering roles have traditionally been separated along the boundary between design and technology. As IC products advance toward higher performance and energy efficiency while the time to market continues to accelerate, future IC engineers will require a deep understanding of the interdependencies between design and technology to expand the product optimization window. ICICDT is the forum for engineers, researchers, professors, and graduate students to cross the design-technology boundary through interactions with design, technology, and process experts to develop the skills for future IC research and development. The unique workshop style of the conference fosters an environment for exchanging breakthrough ideas and collaborating effectively. A one-day tutorial program for both the beginner and expert precedes two days of technical presentations and workshops.
