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.

Microelectronic devices, methods for packaging microelectronic devices, and methods for forming interconnects in microelectronic devices are disclosed herein. In one embodiment, a method comprises providing a microelectronic substrate having a front side and a backside. The substrate has a microelectronic die including an integrated circuit and a terminal operatively coupled to the integrated circuit. The method also includes forming a passage at least partially through the substrate and having an opening at the front side and/or backside of the substrate. The method further includes sealing the opening with a conductive cap that closes one end of the passage while another end of the passage remains open. The method then includes filling the passage with a conductive material.

Microelectronic imaging devices and methods of packaging microelectronic imaging devices are disclosed herein. In one embodiment, a microelectronic imaging device includes a microelectronic die having an integrated circuit, an image sensor electrically coupled to the integrated circuit, and a plurality of bond-pads electrically coupled to the integrated circuit. The imaging device further includes a cover over the image sensor and a plurality of interconnects in and/or on the cover that are electrically coupled to corresponding bond-pads of the die. The interconnects provide external electrical contacts for the bond-pads of the die. The interconnects can extend through the cover or along a surface of the cover.

A probe card for testing semiconductor wafers, and a method and system for testing wafers using the probe card are provided. The probe card is configured for use with a conventional testing apparatus, such as a wafer probe handler, in electrical communication with test circuitry. The probe card includes an interconnect substrate having contact members for establishing electrical communication with contact locations on the wafer. The probe card also includes a membrane for physically and electrically connecting the interconnect substrate to the testing apparatus, and a compressible member for cushioning the pressure exerted on the interconnect substrate by the testing apparatus. The interconnect substrate can be formed of silicon with raised contact members having penetrating projections. Alternately the contact members can be formed as indentations for testing bumped wafers. The membrane can be similar to multi layered TAB tape including metal foil conductors attached to a flexible, electrically-insulating, elastomeric tape. The probe card can be configured to contact all of the dice on the wafer at the same time, so that test signals can be electronically applied to selected dice as required.
摘要:
Multi-chip module systems and method of fabrication thereof wherein the equivalent of a failed die of a multi-chip module (MCM) is added to the module in a vacancy position previously constructed with appropriate electrical connections. A variety of different dice may be attached to the same vacancy position of an MCM by means of adapters, wherein each adapter has the same footprint, but different adapters are capable of accommodating different numbers and types of dice.

A method and apparatus for repair of a multi-chip module, such as a memory module, is provided, where at least one redundant or auxiliary chip attach location is provided on the substrate of the multi-chip module. The auxiliary chip attach location preferably provides contacts for attachment of more than one type of replacement semiconductor chip. Accordingly, when one or more chips on the multi-chip module are found to be completely or partially defective, at least one replacement chip can be selected and attached to the auxiliary location to provide additional memory to bring the module back to its design capacity.
摘要:
A spring element used in a temporary package for testing semiconductors is provided. The spring element is compressed so as to press the semiconductor, either in the form of a bare semiconductor die or as part of a package, against an interconnect structure. The spring element is configured so that it provides sufficient pressure to keep the contacts on the semiconductor in electrical contact with the interconnect structure. Material is added and/or removed from the spring element so that it has the desired modulus of elasticity. The shape of the spring element may also be varied to change the modulus of elasticity, the spring constant, and the force transfer capabilities of the spring element. The spring element also includes conductive material to increase the thermal and electrical conductivity of the spring element.

A temporary package for a semiconductor die is provided. The temporary package has an outline and external contact configuration that are the same as a conventional plastic or ceramic semiconductor package. The temporary package can be used for burn-in testing of the die using standard equipment. The die can then be removed from the package and certified as a known good die. The package includes a base, an interconnect and a force applying mechanism. The package base includes external contacts formed in a dense array, such as a land grid array (LGA), a pin grid array (PGA), a bumped grid array (BGA) or a perimeter array. The package base can be formed of ceramic or plastic with internal conductive lines using a ceramic lamination process, a 3-D molding process or a Cerdip formation process.
