This paper describes a technology platform being developed for three-dimensional (3-D) integration of thin stacked silicon integrated circuits (ICs). 3-D integration technology promises to dramatically enhance on-chip signal processing capabilities of a variety of sensor and actuator array devices hybridized with silicon read-out electronics. Currently, advanced 3-D integrated infrared focal plane array detectors are being developed within the DARPA vertically integrated sensor arrays (VISA) program. Here, we describe the 3-D integration process flow and demonstrations developed in the VISA program.
