摘要:
A through-wafer interconnect for imager, memory and other integrated circuit applications is disclosed, thereby eliminating the need for wire bonding, making devices incorporating such interconnects stackable and enabling wafer level packaging for imager devices. Further, a smaller and more reliable die package is achieved and circuit parasitics (e.g., L and R) are reduced due to the reduced signal path lengths.

Materials for use in programmed material consolidation processes, such as stereolithography, include a selectively consolidatable material and a filler. The filler may be included to optimize one or more physical properties of the material. The material is both selectively consolidatable and includes the desired physical property. Examples of physical properties that may optimized in a selectively consolidatable compound by mixing a filler material with a selectively consolidatable material include, without limitation, coefficient of thermal expansion, rigidity, fracture toughness, thermal stability, and strength.

摘要:
Methods for optimizing physical properties of selectively consolidatable materials, such as photoimageable materials, include mixing filler materials with the selectively consolidatable materials. The resulting compound has the desired physical property, as well as selective consolidatability. Examples of physical properties that may optimized in a selectively consolidatable compound by mixing a filler material with a selectively consolidatable material include, without limitation, coefficient of thermal expansion, rigidity, fracture toughness, thermal stability, and strength.
摘要:
A support structure for use with a semiconductor substrate in thinning, or backgrinding, thereof, as well as during post-thinning processing of the semiconductor substrate includes a portion which extends substantially along and around an outer periphery of the semiconductor substrate to impart the thinned semiconductor substrate with rigidity. The support structure may be configured as a ring or as a member which substantially covers an active surface of the semiconductor substrate and forms a protective structure over each semiconductor device carried by the active surface.

A compliant contact pin contactor card method for making is provided. A 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.

摘要:
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.
