    摘要: An optical grating is disposed on a waveguide to redirect light from the interior of the waveguide through the opposite side of the waveguide from the grating. In one embodiment the waveguide, the grating, and an optical sensor are combined in a single monolithic structure. In another embodiment, an absorbing layer is directly connected to the waveguide in the region of the grating. In still another embodiment, efficiency of the grating is improved by having a high index contrast between the refractive index of the grating and the refractive index of the cladding disposed over the grating, and by having an appropriately sized discontinuity in the grating.

    摘要: A method and semiconductor device for integrating the fabrication of a photodetector with the fabrication of a CMOS device on a SOI substrate. The SOI substrate is divided into two regions, a CMOS region and an optical detecting region. After the CMOS device is fabricated in the CMOS region, the optical detecting region is patterned and etched through the top silicon layer and the buried oxide layer to the base silicon layer. The pattern is etched to a depth so that after a material of a photodetector is deposited in the etched pattern, the material grows to the surface level of the SOI substrate. After the formation of a photodetector structure in the optical detecting region, the metallization process is performed on the CMOS device and the photodetector. In this manner, the fabrication of a photodetector is integrated with the fabrication of a CMOS device on the SOI substrate.
