Abstract
Three-dimensional (3D) integration is an emerging technology that vertically stacks and interconnects multiple materials, technologies and functional components to form highly integrated micro/nano-systems. This paper reviews the materials and technologies for three wafer bonding approaches to 3D integration using adhesive, metal, and metal/adhesive as the bonding interfaces. Similarities and differences in architectural advantages and technology challenges are presented, with recent research advances discussed.
