Abstract

The realization of monolithic optical interconnects by integration of III-V materials with conventional Si circuitry has long been hindered by materials incompatibilities (i.e. lattice mismatch and heterovalent interface) and practical processing constraints. We have demonstrated successful integration of hetero-epitaxially grown InGaAs/Si diodes with an n-well CMOS process on (001) Si offcut 6 degrees towards [110]. The In_0.15Ga_0.85As/In_xGa_{1- x}As/GaAs/Si diodes were grown by atmospheric pressure organo-metallic chemical vapor deposition (OMCVD) and features a room temperature R₀A product of 20,000 ohm-cm². No degradation of PMOS or NMOS transistor characteristics was detected upon integration of the III-V devices. Further improvement of III-V/Si device characteristics are anticipated in future efforts by incorporating relaxed, compositionally- graded Ge/Ge_xSi_1-x/Si with low threading dislocation densities (approximately 2 X 10⁶/cm²) to bridge the gap in lattice constants between Si and GaAs. Recent progress towards this end includes the suppression of antiphase disorder during GaAs growth on Ge/Ge_xSi_1-x/Si by OMCVD and strong room temperature photoluminescence from In_0.20Ga_0.80As QW test structures on GaAs/Ge_xSi_{1- x}/Si at 920 nm.
