Abstract
An integrated camera module (10, 10a) for capturing video images in very small digital cameras, cell phones, personal digital assistants, and the like. A lens assembly (24, 24a) is rigidly affixed in relation to a sensor array area (14) of a camera chip (12) by a molding (26). The molding (26) is formed on the camera chip (12), and optionally on a printed circuit board (16, 16a) on which the camera chip (12) is mounted. The lens assembly (24, 24a) is held in place in a recess (29) of the molding (26) by an adhesive (28). The molding (26) is formed such that a precise gap (30) exists between the lens assembly (24) and a sensor array area (14) of the camera chip (12). In a particular embodiment, lens holders (306, 506) are formed entirely on the camera chips (302, 502) before or after they are separated from one another.
