3D IC Pixel Electronics- the Next Challenge

There is no question that 3D integrated circuit design will play an important role in the continuing development of high performance integrated circuits. This paper will provide a brief introduction to the markets for 3D integrated circuits and the technologies that are used, followed by a review of 3D activities in High Energy Physics (HEP). The paper will review the first 3D chip for HEP and conclude with discussion of a collaborative effort to use a commercial vendor to fabricate 3D ICs as a path forward to meet the next challenge for electronics designers in HEP .
