    Abstract

    A study is presented on silicon oxynitride material for waveguides and germanium-silicon alloys for p-i-n diodes. The materials are manufactured at low, CMOS-backend compatible temperatures, targeting the integration of optical functions on top of CMOS chips. Low-temperature germanium-silicon deposition, crystallization and doping are studied for integrated photodetection up to ~1500 nm wavelength. An inductivelycoupled-plasma chemical vapor deposition process is presented for silicon oxynitride manufacturing at 150 °C wafer temperature, yielding low-loss material in a wide optical spectral range. Integration schemes for an optical plane on top of CMOS are discussed.
