Abstract

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