摘要： Interconnection elements for electronic components, exhibiting desirable mechanical characteristics (such as resiliency, for making pressure contacts) are formed by shaping an elongate element (core) of a soft material (such as gold) to have a springable shape (including cantilever beam, S-shape, U-shape), and overcoating the shaped elongate element with a hard material (such as nickel and its alloys), to impart a desired spring (resilient) characteristic to the resulting composite interconnection element. A final overcoat of a material having superior electrical qualities (e.g., electrical conductivity and/or solderability) may be applied to the composite interconnection element. The elongate element may be formed from a wire, or from a sheet (e.g., metal foil). The resulting interconnection elements may be mounted to a variety of electronic components, including directly to semiconductor dies and wafers (in which case the overcoat material anchors the composite interconnection element to a terminal (or the like) on the electronic component), may be mounted to support substrates for use as interposers and may be mounted to substrates for use as probe cards or probe card inserts. In one embodiment, a hybrid composite interconnection element is formed by mounting a core to an end of an flat elongate element formed from a sheet, and overcoating at least the core, the flat elongate element providing a "floating" support for the overcoated core, capable of absorbing non-planarities (tolerances) of an electronic component. Methods of fabricating interconnection elements on sacrificial substrates are described. Methods of fabricating tip structures and contact tips at the end of interconnection elements are described.

摘要： A flowable coating material, such as a liquid having solids in suspension, such as spin-on glass, is applied to a surface of an electronic component by placing the component in a centrifuge and spinning the component about a first axis so that the liquid material is forced against the surface of the component. The component may also be rotated about its own axis so that the liquid material is distributed along the surface of the component.

摘要： Resilient contact structures are mounted directly to bond pads on semiconductor dies, prior to the dies being singulated (separated) from a semiconductor wafer. This enables the semiconductor dies to be exercised (e.g., tested and/or burned-in) by connecting to the semiconductor dies with a circuit board or the like having a plurality of terminals disposed on a surface thereof. Subsequently, the semiconductor dies may be singulated from the semiconductor wafer, whereupon the same resilient contact structures can be used to effect interconnections between the semiconductor dies and other electronic components (such as wiring substrates, semiconductor packages, etc.). Using the all-metallic composite interconnection elements of the present invention as the resilient contact structures, burn-in can be performed at temperatures of at least 150.degree. C., and can be completed in less than 60 minutes.

摘要： One or more customization layers can be added to a wiring substrate. The customization layers can provide customized electrical connections from electrical contacts of the base wiring substrate to electrical contacts at an outer surface of the customization layers, which can allow the contacts at the outer surface of the customization layers can be in a different pattern than the contacts at the surface of the base wiring substrate. The customization layers can comprise electrically insulating material, electrically conductive via structures through the insulating material, electrically conductive traces, electrically conductive jumpers electrically connecting two traces without contacting a trace disposed between the two traces, and/or other such elements. A jumper can be formed by making a relatively small deposit of electrically insulating material between the two traces to be connected and then making a relatively small deposit of electrically conductive material on parts of the two traces and the insulating material. Via structures can be coupled to traces and an insulating material can be cast around the via structures. Alternatively, via structures can be formed in openings with sloped side walls in an insulating layer.

摘要： Contact structures exhibiting resilience or compliance for a variety of electronic components are formed by bonding a free end of a wire to a substrate, configuring the wire into a wire stem having a springable shape, severing the wire stem, and overcoating the wire stem with at least one layer of a material chosen primarily for its structural (resiliency, compliance) characteristics. A variety of techniques for configuring, severing, and overcoating the wire stem are disclosed. In an exemplary embodiment, a free end of a wire stem is bonded to a contact area on a substrate, the wire stem is configured to have a springable shape, the wire stem is severed to be free-standing by an electrical discharge, and the free-standing wire stem is overcoated by plating. A variety of materials for the wire stem (which serves as a falsework) and for the overcoat (which serves as a superstructure over the falsework) are disclosed. Various techniques are described for mounting the contact structures to a variety of electronic components (e.g., semiconductor wafers and dies, semiconductor packages, interposers, interconnect substrates, etc.), and various process sequences are described. The resilient contact structures described herein are ideal for making a “temporary” (probe) connections to an electronic component such as a semiconductor die, for burn-in and functional testing. The self-same resilient contact structures can be used for subsequent permanent mounting of the electronic component, such as by soldering to a printed circuit board (PCB). An irregular topography can be created on or imparted to the tip of the contact structure to enhance its ability to interconnect resiliently with another electronic component. Among the numerous advantages of the present invention is the great facility with which the tips of a plurality of contact structures can be made to be coplanar with one another. Other techniques and embodiments, such as wherein the falsework wirestem protrudes beyond an end of the superstructure, or is melted down, and wherein multiple free-standing resilient contact structures can be fabricated from loops, are described.

摘要： Spring contact elements are fabricated by depositing at least one layer of metallic material into openings defined on a sacrificial substrate. The openings may be within the surface of the substrate, or in one or more layers deposited on the surface of the sacrificial substrate. Each spring contact element has a base end portion, a contact end portion, and a central body portion. The contact end portion is offset in the z-axis (at a different height) than the central body portion. The base end portion is preferably offset in an opposite direction along the z-axis from the central body portion. In this manner, a plurality of spring contact elements are fabricated in a prescribed spatial relationship with one another on the sacrificial substrate. The spring contact elements are suitably mounted by their base end portions to corresponding terminals on an electronic component, such as a space transformer or a semiconductor device, whereupon the sacrificial substrate is removed so that the contact ends of the spring contact elements extend above the surface of the electronic component. In an exemplary use, the spring contact elements are thereby disposed on a space transformer component of a probe card assembly so that their contact ends effect pressure connections to corresponding terminals on another electronic component, for the purpose of probing the electronic component.

摘要： Resilient spring contact structures are manufactured by plating the contact structures on a reusable mandrel, as opposed to forming the contact structures on sacrificial layers that are later etched away. In one embodiment, the mandrel includes a form or mold area that is inserted through a plated through hole in a substrate. Plating is then performed to create the spring contact on the mold area of the mandrel as well as to attach the spring contact to the substrate. In a second embodiment, the mandrel includes a form that is initially plated to form the resilient contact structure and then attached to a region of a substrate without being inserted through the substrate. Attachment in the second embodiment can be achieved during the plating process used to form the spring contact, or by using a conductive adhesive or solder either before or after releasing the spring contact from the mandrel.
