A semiconductor component includes a semiconductor substrate having a substrate contact, and a through wire interconnect (TWI) bonded to the substrate contact. The through wire interconnect (TWI) includes a via through the substrate contact and the substrate, a wire in the via bonded to the substrate contact, and a contact on the wire. A stacked semiconductor component includes the semiconductor substrate, and a second semiconductor substrate stacked on the substrate and bonded to a through wire interconnect on the substrate. A method for fabricating a semiconductor component with a through wire interconnect includes the steps of providing a semiconductor substrate with a substrate contact, forming a via through the substrate contact and part way through the substrate, placing the wire in the via, bonding the wire to the substrate contact, and then thinning the substrate from a second side to expose a contact on the wire. A system for fabricating the semiconductor component includes a bonding capillary configured to place the wire in the via, and to form a bonded connection between the wire and the substrate contact.

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.

Methods of packaging microelectronic imagers and packaged microelectronic imagers. An embodiment of such a method can include providing an imager workpiece having a plurality of imager dies arranged in a die pattern and providing a cover substrate through which a desired radiation can propagate. The imager dies include image sensors and integrated circuitry coupled to the image sensors. The method further includes providing a spacer having a web that includes an adhesive and has openings arranged to be aligned with the image sensors. For example, the web can be a film having an adhesive coating, or the web itself can be a layer of adhesive. The method continues by assembling the imager workpiece with the cover substrate such that (a) the spacer is between the imager workpiece and the cover substrate, and (b) the openings are aligned with the image sensors. The attached web is not cured after the imager workpiece and the cover substrate have both been adhered to the web. As such, the web does not outgas contaminants into the compartments in which the image sensors are housed.

A semiconductor package such as an image sensor package, and methods for fabrication. A frame structure includes an array of frames, each having an aperture therethrough, into which an image sensor die in combination with a cover glass, filter, lens or other components may be installed in precise mutual alignment. Singulated image sensor dice and other components may be picked and placed into each frame of the frame structure. Alternatively, the frame structure may be configured to be aligned with and joined to a wafer bearing a plurality of image sensor dice, wherein optional, downwardly protruding skirts along peripheries of the frames may be received into kerfs cut along streets between die locations on the wafer, followed by installation of other package components. In either instance, the frame structure in combination with singulated image sensor dice or a joined wafer is singulated into individual image sensor packages. Various external connection approaches may be used for the packages.

A reusable burn-in/test fixture for testing unsingulated dice on a semiconductor wafer consisting of two halves. The first half of the test fixture is a wafer cavity plate for receiving the wafer, and the second half establishes electrical communication between the wafer and electrical testing equipment. A rigid substrate has conductors thereon which establish electrical contact with the wafer. The test fixture need not be opened until the burn-in and electrical testing are completed. After burn-in stress and electrical testing, it is possible to establish interconnection between the single die or separate and package dice into discrete parts, arrays or clusters, either as singulated parts or as arrays.

A compliant contact pin assembly and a contactor card system are 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.
