    摘要: Methods and systems for monolithic integration of photonics and electronics in CMOS processes are disclosed and may include fabricating photonic and electronic devices on two CMOS wafers with different silicon layer thicknesses for the photonic and electronic devices bonded to at least a portion of each of the wafers together, where a first of the CMOS wafers includes the photonic devices and a second of the CMOS wafers includes the electronic devices. The electrical devices may be coupled to optical devices utilizing through-silicon vias. The different thicknesses may be fabricated utilizing a selective area growth process. Cladding layers may be fabricated utilizing oxygen implants and/or utilizing CMOS trench oxide on the CMOS wafers. Silicon may be deposited on the CMOS trench oxide utilizing epitaxial lateral overgrowth. Cladding layers may be fabricated utilizing selective backside etching. Reflective surfaces may be fabricated by depositing metal on the selectively etched regions.

    摘要: Methods and systems for monolithic integration of photonics and electronics in CMOS processes are disclosed and may include fabricating photonic and electronic devices on a single CMOS wafer with different silicon layer thicknesses. The devices may be fabricated on a semiconductor-on-insulator (SOI) wafer utilizing a bulk CMOS process and/or on a SOI wafer utilizing a SOI CMOS process. The different thicknesses may be fabricated utilizing a double SOI process and/or a selective area growth process. Cladding layers may be fabricated utilizing one or more oxygen implants and/or utilizing CMOS trench oxide on the CMOS wafer. Silicon may be deposited on the CMOS trench oxide utilizing epitaxial lateral overgrowth. Cladding layers may be fabricated utilizing selective backside etching. Reflective surfaces may be fabricated by depositing metal on the selectively etched regions. Silicon dioxide or silicon germanium integrated in the CMOS wafer may be utilized as an etch stop layer.
