CMOS image sensor using gradient index chip scale lenses
A camera module (100, 200) includes a gradient index lens (160) on a spacer plate (150) attached over an array of pixel sensors (120) and associated micro lenses (130, 230). The spacer plate (150) and gradient index lens (160) can be formed at the wafer level during the manufacture of multiple camer...

| description | A camera module (100, 200) includes a gradient index lens (160) on a spacer plate (150) attached over an array of pixel sensors (120) and associated micro lenses (130, 230). The spacer plate (150) and gradient index lens (160) can be formed at the wafer level during the manufacture of multiple camera modules (100, 200). A process for manufacturing the camera modules (100, 200) thus provides tolerances and yields provided by wafer processing techniques rather than mechanical assembly. |
