Low magnification SEM image of interconnected Si photodetector pixels and electronics on substrate.
Low magnification scanning electron micrograph of a collection of silicon photodetector pixels and electronics interconnected by arc-shaped ribbons, on a hemispherical substrate. These interconnects bow upward to accommodate the large mechanical strains needed to transform the planar layouts in which the systems are initially fabricated to the hemispherical geometries needed for implementation in the electronic eye. The image is colorized: pixel elements and interconnects appear gold; the substrate appears light blue.
