Advanced heterogeneous integration of InP HBT and CMOS Si technologies for high performance mixed signal applications

Northrop Grumman Space Technology (NGST) is developing an advanced heterogeneous integration (AHI) process to integrate III-V semiconductor chiplets on CMOS wafers under the compound semiconductor materials on silicon (COSMOS) DARPA program. The objective of the program is to have a heterogeneous interconnect pitch and length less than 5 um to enable intimate transistor scale integration. This integration will enable significant improvement in ADC dynamic range and bandwidth.
