摘要： A method of making a microelectronic spring contact array comprises forming a plurality of spring contacts on a sacrificial substrate and then releasing the spring contacts from the sacrificial substrate. Each of the spring contacts has an elongated beam having a base end. The method of making the array includes attaching the spring contacts at their base ends to a base substrate after they have been released entirely from the sacrificial substrate, so that each contact extends from the base substrate to a distal end of its beams. The distal ends are aligned with a predetermined array of tip positions. In an embodiment of the invention, the spring contacts are formed by patterning contours of the spring contacts in a sacrificial layer on the sacrificial substrate. The walls of patterned recesses in the sacrificial layer define side profiles of the spring contacts, and a conductive material is deposited in the recesses to form the elongated beams of the spring contacts.

摘要： Resilient spring contacts for use in wafer test probing are provided that can be manufactured with a very fine pitch spacing and precisely located on a support substrate. The resilient contact structures are adapted for wire bonding to an electrical circuit on a space transformer substrate. The support substrates with attached spring contacts can be manufactured together in large numbers and diced up and tested before attachment to a space transformer substrate to improve yield. The resilient spring contacts are manufactured using photolithographic techniques to form the contacts on a release layer, before the spring contacts are epoxied to the support substrate and the release layer removed. The support substrate can be transparent to allow alignment of the contacts and testing of optical components beneath. The support substrate can include a ground plane provided beneath the spring contacts for improved impedance matching.

摘要： Contact tip structures are fabricated on sacrificial substrates for subsequent joining to interconnection elements including composite interconnection elements, monolithic interconnection elements, tungsten needles of probe cards, contact bumps of membrane probes, and the like. The spatial relationship between the tip structures can lithographically be defined to very close tolerances. The metallurgy of the tip structures is independent of that of the interconnection element to which they are attached, by brazing, plating or the like. The contact tip structures are readily provided with topological (small, precise, projecting, non-planar) contact features, such as in the form of truncated pyramids, to optimize electrical pressure connections subsequently being made to terminals of electronic components. Elongate contact tip structures, adapted in use to function as spring contact elements without the necessity of being joined to resilient contact elements are described. Generally, the invention is directed to making (pre-fabricating) relatively ‘perfect’ contact tip structures (“tips”) and joining them to relatively ‘imperfect’ interconnection elements to improve the overall capabilities of resulting “tipped” interconnection elements.

摘要： A robust mechanical structure is provided to prevent small foundation structures formed on a substrate from detaching from the substrate surface. The strengthened structure is formed by plating a foundation metal layer on a seed layer and then embedding the plated foundation structure in an adhesive polymer material, such as epoxy. Components, such as spring probes, can then be constructed on the plated foundation. The adhesive polymer material better assures the adhesion of the metal foundation structure to the substrate surface by counteracting forces applied to an element, such as a spring probe, attached to the plated foundation.

摘要： A wafer test assembly includes multiple probe head substrates arranged like tiles with connectors attached to one side and probes supported on the opposing side. In one embodiment, flexible cable connectors directly connect the connectors on the probe head tile to a test head, while in another embodiment the flexible cables connect the probe head tile to a PCB providing horizontal routing to test head connectors. In one embodiment, leveling pins provide a simplified support structure connecting to a retaining element attached to the tiles to provide for applying a push-pull leveling force. A test head connector interface frame enables rearrangement of connectors between the test head and the probe card to provide for both full wafer contact or partial wafer contact. The test head connectors are rearranged by being slidable on rails, or pluggable and unpluggable enabling movement over a range of positions.

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.
