Developing an application for 3D IC chip stacking technology

— How to shift from fundamental to practical technology —

Abstract

3D IC chip stacking technology is expected to be the future of electronic device integration technology, because integration along the additional dimension affords efficient use of space and improvement of system architecture. We developed fundamental technology of high density integration for 3D IC chip stacking. To facilitate applications of this technology, a mass-production process was developed in collaboration with a production system company.
