A MEMS auto focus miniature camera module includes an image sensor and an optical train including at least one movable lens and one or more fixed lenses or fixed lens groups on either side of the movable lens. The movable lens provides an auto focus feature of the camera module. A MEMS actuator translates the movable lens through an auto focus range to adjust focus.

MEMS auto focus miniature camera module with fixed and movable lens groups

A miniature MEMS autofocus camera module includes a MEMS actuated movable lens group and at least one fixed lens group defining an optical axis within a camera module housing. Objects disposed an arbitrary distance from the camera module are automatically focused at a determined zoom to an image sensor. MEMS actuation of the movable lens group is performed to accomplish autofocus functionality.

Miniature camera module with MEMS-actuated autofocus

A miniature camera module component is formed by creating replicated lens shapes on a protective cover wafer and depositing material to form multiple cavities with the replicated lens shapes respectively disposed therein. A carrier wafer is coupled to the protective cover wafer before it is diced. An intermediate wafer is coupled to the protective cover wafer, and the carrier wafer is removed. An image sensor wafer is coupled to the protective cover wafer, and the intermediate wafer is removed.
