ABSTRACT

3D and 2.5D integration technologies permit substantial improvement in form factor, power, performance, functionality, and sometimes even cost. Though not providing a direct replacement for Moore’s law, 3D technologies can permit a generation or more of exponential scaling in power per unit of performance and other factors. This chapter is structured as follows. First, there is a review of 3D technologies, followed by a general discussion of commercial 3D success stories and technology drivers. We review 3D logic projects conducted at North Carolina State University, Raleigh, North Carolina, before closing out on heterogeneous integration.
