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.

A microelectronic unit includes a semiconductor element having a front surface to which a packaging layer is attached, and a rear surface remote from the front surface. The element includes a light detector including a plurality of light detector element arranged in an array disposed adjacent to the front surface and arranged to receive light through the rear surface. The semiconductor element also includes an electrically conductive contact at the front surface connected to the light detector. The conductive contact includes a thin region and a thicker region which is thicker than the thin region. A conductive interconnect extends through the packaging layer to the thin region of the conductive contact, and a portion of the conductive interconnect is exposed at a surface of the microelectronic unit.

An actuator that operates by electrostatic attraction and repulsion and can have fixed and moving electrodes is disclosed for one or more embodiments. The fixed and moving electrodes can be inclined relative to each other at an acute angle. The actuator can be radially symmetric and mirrored about the moving electrode. The moving electrode can have a central aperture over which is placed an optical element such as a lens. The optical element can be part of an optical train that permits the focus of an electronic camera to be modified by changing the displacement of the lens along the optical axis of the camera.

By selecting different materials for each layer, a multi-layered electrode structure can be made with superior performance characteristics. For example, a multilayered electrode can include a high tensile strength tungsten core, a conductive intermediate palladium, palladium-nickel, or other platinum group metal layer for generating a corona discharge, and a hardened layer comprising rhodium or other platinum group metal or alloy of the same to resist frictional abrasion during removal of silica dendrites that accumulate on the electrode surface during operation.
摘要:
Improved packages for light emitters may be fabricated at the wafer level. The package can be a single device or an array of die. The package includes a thermal via that extends through the thickness of the package substrate. The thermal via may be made of a material possessing a high thermal conductivity. The thermal via may be wider at the package exterior than at the interior to provide heat spreading between the device and its heat sink. The taper angle of the thermal via may be around 45 degrees to match the natural spread of heat in a solid. The thermal via may extend above the package interior, so its height is sufficient to position an emitter placed thereon at one foci of a parabola, where the vertex of the parabola is at the surface of the package substrate from which the thermal via extends.

Packaged microelectronic elements are provided. In an exemplary embodiment, a microelectronic element having a front face and a plurality of peripheral edges bounding the front face has a device region at the front face and a contact region with a plurality of exposed contacts adjacent to at least one of the peripheral edges. The packaged element may include a plurality of support walls overlying the front face of the microelectronic element such that a lid can be mounted to the support walls above the microelectronic element. For example, the lid may have an inner surface confronting the front face. In a particular embodiment, some of the contacts can be exposed beyond edges of the lid.
摘要:
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.
