摘要:
Microelectronic imagers and methods for packaging microelectronic imagers are disclosed herein. In one embodiment, a microelectronic imaging unit can include a microelectronic die, an image sensor, an integrated circuit electrically coupled to the image sensor, and a bond-pad electrically coupled to the integrated circuit. An electrically conductive through-wafer interconnect extends through the die and is in contact with the bond-pad. The interconnect can include a passage extending completely through the substrate and the bond-pad with conductive fill material at least partially disposed in the passage. An electrically conductive support member is carried by and projects from the bond-pad. A cover over the image sensor is coupled to the support member.

A semiconductor component includes a base die and a secondary die stacked on and bonded to the base die. The base die includes conductive vias which form an internal signal transmission system for the component, and allow the circuit side of the secondary die to be bonded to the back side of the base die. The component also includes an array of terminal contacts on the circuit side of the base die in electrical communication with the conductive vias. The component can also include an encapsulant on the back side of the base die, which substantially encapsulates the secondary die, and a polymer layer on the circuit side of the base die which functions as a protective layer, a rigidifying member and a stencil for forming the terminal contacts. A method for fabricating the component includes the step of bonding singulated secondary dice to base dice on a base wafer, or bonding a secondary wafer to the base wafer, or bonding singulated secondary dice to singulated base dice.

A compliant contact pin assembly and a contactor card system are provided. The compliant contact pin assembly includes a contact pin formed from a portion of a substrate with the contact pin compliantly held suspended within the substrate by a compliant coupling structure. The suspension within the substrate results in a compliant deflection orthogonal to the plane of the substrate. The contact pin assembly is formed by generally thinning the substrate around the contact pin location and then specifically thinning the substrate immediately around the contact pin location for forming a void. The contact pin is compliantly coupled, in one embodiment by compliant coupling material, and in another embodiment by compliantly flexible portions of the substrate.

Microelectronic imager assemblies comprising a workpiece including a substrate and a plurality of imaging dies on and/or in the substrate. The substrate includes a front side and a back side, and the imaging dies comprise imaging sensors at the front side of the substrate and external contacts operatively coupled to the image sensors. The microelectronic imager assembly further comprises optics supports superimposed relative to the imaging dies. The optics supports can be directly on the substrate or on a cover over the substrate. Individual optics supports can have (a) an opening aligned with one of the image sensors, and (b) a bearing element at a reference distance from the image sensor. The microelectronic imager assembly can further include optical devices mounted or otherwise carried by the optics supports.
