An electronic camera module incorporates a sensor unit (20) having a semiconductor chip (22) such as a CCD imager and a cover (34) overlying the front surface of the chip. An optical unit (50) includes one or more optical elements such as lenses (58). The optical unit has engagement features (64) which abut alignment features on the sensor unit as, for example, portions (44) of the cover outer surface (38), so as to maintain a precise relationship between the optical unit and sensor unit.

Lidded chip packages are provided in which an optoelectronic device chip has microelectronic circuits exposed at a surface of the chip with a lid mounted to overlie the optoelectronic device and the microelectronic circuits. An opaque film may be attached to the lid to overlie the microelectronic circuits while exposing the optoelectronic device. Lidded chip packages are also provided in which the lid overlies an active or passive device mounted to the chip. Wiring traces may be embedded within an adhesive between the lid and the chip.

摘要:
An electronic camera module includes a lens or refractive element formed by a pair of immiscible liquids and having optical properties which can be varied by applying a voltage so as to deform the meniscus. One of the two liquids extends from the meniscus all the way to the front surface of the sensor, so that light passing through the meniscus does not encounter further changes in refractive index enroute to the sensor.

Capped chips and methods of forming a capped chip are provided in which electrical interconnects are made by conductive elements which extend from bond pads of a chip at least partially through a plurality of through holes of a cap. The electrical interconnects may be solid, so as to form seals extending across the through holes. In some cases, stud bumps extend from the bond pads, forming parts of the electrical interconnects. In some cases, a fusible conductive medium forms a part of the electrical interconnects.
