Abstract: Surface-mount, solder-down sockets are described which permit electronic components such as semiconductor packages to be releasably mounted to a circuit board. Generally, the socket includes resilient contact structures extending from a top surface of a support substrate, and solder-ball (or other suitable) contact structures disposed on a bottom surface of the support substrate. Composite interconnection elements are described for use as the resilient contact structures disposed atop the support substrate. In use, the support substrate is soldered down onto the circuit board, the contact structures on the bottom surface of the support substrate contacting corresponding contact areas on the circuit board. In any suitable manner, selected ones of the resilient contact structures atop the support substrate are connected, via the support substrate, to corresponding ones of the contact structures on the bottom surface of the support substrate. For example, the support substrate is suitably a printed circuit board having plated through holes. In an embodiment intended to receive a LGA-type semiconductor package, pressure contact is made between the resilient contact structures and external connection points of the semiconductor package with a contact force which is generally normal to the top surface of the support substrate. In an embodiment intended to receive a BGA-type semiconductor package, pressure contact is made between the resilient contact structures and external connection points of the semiconductor package with a contact force which is generally parallel to the top surface of the support substrate. Variations of these two basic embodiments are described, including limiting wiping motion of the resilient contact structures across a terminal of an electronic component, and moving the resilient contact structures rather than the electronic component to effect pressure connections therebetween.

Abstract: A method for replacing a microelectronic spring contact bonded to a terminal of a substrate is disclosed. The method comprises removing the microelectronic spring contact from the terminal, such as by cutting the microelectronic spring contact in two adjacent to the terminal. Then, a bonding material, such as a solder paste, is applied to the terminal and a replacement spring contact is positioned on the bonding material. The bonding material is then cured to fix the replacement spring contact in place. The replacement spring contact includes a base configured to fit on or over any protruding material left on the terminal, and at least one resilient cantilever arm extending from the base. In an embodiment of the invention, the base comprises at least two legs extending from the base in a direction opposite to the cantilever arm. In an alternative embodiment, the base of the replacement spring contact has a flat bottom, or one or more recesses to receive protrusions on the terminal. The replacement spring contact is positioned with its base opposite to the terminal and the resilient cantilever arm extending away from the substrate. A method for forming a suitable replacement spring contact is also disclosed.

Abstract: A probe card assembly includes a probe card, a space transformer having resilient contact structures (probe elements) mounted directly to (i.e., without the need for additional connecting wires or the like) and extending from terminals on a surface thereof, and an interposer disposed between the space transformer and the probe card. The space transformer and interposer are nullstacked upnull so that the orientation of the space transformer, hence the orientation of the tips of the probe elements, can be adjusted without changing the orientation of the probe card. Suitable mechanisms for adjusting the orientation of the space transformer, and for determining what adjustments to make, are disclosed. The interposer has resilient contact structures extending from both the top and bottom surfaces thereof, and ensures that electrical connections are maintained between the space transformer and the probe card throughout the space transformer's range of adjustment, by virtue of the interposer's inherent compliance. Multiple die sites on a semiconductor wafer are readily probed using the disclosed techniques, and the probe elements can be arranged to optimize probing of an entire wafer. Composite interconnection elements having a relatively soft core overcoated by a relatively hard shell, as the resilient contact structures are described.

Abstract: 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.

Abstract: A method of designing and manufacturing a probe card assembly includes prefabricating one or more elements of the probe card assembly to one or more predefined designs. Thereafter, design data regarding a newly designed semiconductor device is received along with data describing the tester and testing algorithms to be used to test the semiconductor device. Using the received data, one or more of the prefabricated elements is selected. Again using the received data, one or more of the selected prefabricated elements is customized. The probe card assembly is then built using the selected and customized elements.

Abstract: An interconnection element of a spring (body) including a first resilient element with a first contact region and a second contact region and a first securing region and a second resilient element, with a third contact region and a second securing region. The second resilient element is coupled to the first resilient element through respective securing regions and positioned such that upon sufficient displacement of the first contact region toward the second resilient element, the second contact region will contact the third contact region. The interconnection, in one aspect, is of a size suitable for directly contacting a semiconductor device. A large substrate with a plurality of such interconnection elements can be used as a wafer-level contactor. The interconnection element, in another aspect, is of a size suitable for contacting a packaged semiconductor device, such as in an LGA package.

Abstract: Microelectronic contact structures are fabricated by separately forming, then joining together, various components thereof. Each contact structure has three components: a nullpostnull component, a nullbeamnull component, and a nulltipnull component. The resulting contact structure, mounted to an electronic component, is useful for making an electrical connection with another electronic component. The post component can be fabricated on a sacrificial substrate, joined to the electronic component and its sacrificial substrate removed. Alternatively, the post component can be formed on the electronic component. The beam and tip components can each be fabricated on a sacrificial substrate. The beam component is joined to the post component and its sacrificial substrate is removed, and the tip component is joined to the beam component and its sacrificial substrate is removed.

Abstract: 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 150null C., and can be completed in less than 60 minutes.
