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： A method of fabricating a large contactor (62) is provided wherein one or more contactor units (78) are mounted on a support substrate (74) such that contact elements (80) attached to the contactor units are suitably aligned. In this manner, a large area contactor can be prepared using a plurality of smaller contactor units. Preferably the contact elements on the plurality of contactor units are coplanar across the contactor units. This is particularly advantageous for making a large contactor for probing semiconductor devices on a wafer. This also can be useful for making a contactor capable of contacting devices across an entire semiconductor wafer. In one embodiment, the contactor units self-align during reflow of a joining material such as solder balls (134) or other reflowable material interconnecting the contactor units and the support substrate. In alternative embodiments, alignment facilitation devices such as keys (154) and indentations (156) are utilized to assist the alignment of the contactor units.
