Recent advances in monolithic integration of diverse technologies with Si CMOS

HRL Laboratories is part of an intense research and development effort to leverage the enormously advanced infrastructure of Si CMOS and the high performance of diverse electronic and photonic devices in an integrated technology. While System in a Package (SiP) and System on a Chip (SoC) approaches involve chips produced in their native foundries and subsequent integration using hybridization or multi-chip modules, HRL has pioneered approaches where partially completed wafers of diverse technologies are integrated using highly intimate placement and heterogeneous interconnects to enable transistor-level integration. Novel ICs have been produced in InP BiCMOS and CMOS memristor-integrated technologies. Unprecedented design flexibility is being enabled with intimate integration of GaN HEMTs together with InP and CMOS.
