a Microfabrication methods of the MOE, formed by using repeated photolithography and thermal reflow. The MOE was further integrated on a CMOS image sensor with gap spacers by using a flip-chip bonder. b Scanning electron microscopy and c optical microscopy images of microlens arrays. The white dots on the captured optical image display focused beams through the iMLAs. d A cross-sectional optical image of the MOE. e A captured photograph of a fully packaged ultrathin arrayed camera
