Abstract: A probe card assembly comprises multiple probe substrates attached to a mounting assembly. Each probe substrate includes a set of probes, and together, the sets of probes on each probe substrate compose an array of probes for contacting a device to be tested. Adjustment mechanisms are configured to impart forces to each probe substrate to move individually each substrate with respect to the mounting assembly. The adjustment mechanisms may translate each probe substrate in an “x,” “y,” and/or “z” direction and may further rotate each probe substrate about any one or more of the forgoing directions. The adjustment mechanisms may further change a shape of one or more of the probe substrates. The probes can thus be aligned and/or planarized with respect to contacts on the device to be tested.

Abstract: A probe card assembly can include a probe head assembly having probes for contacting an electronic device to be tested. The probe head assembly can be electrically connected to a wiring substrate and mechanically attached to a stiffener plate. The wiring substrate can provide electrical connections to a testing apparatus, and the stiffener plate can provide structure for attaching the probe card assembly to the testing apparatus. The stiffener plate can have a greater mechanical strength than the wiring substrate and can be less susceptible to thermally induced movement than the wiring substrate. The wiring substrate may be attached to the stiffener plate at a central location of the wiring substrate. Space may be provided at other locations where the wiring substrate is attached to the stiffener plate so that the wiring substrate can expand and contract with respect to the stiffener plate.

Abstract: 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.

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: The present invention provides an ancillary electrical component in very close proximity to a semiconductor device, preferably mounted directly to the semiconductor device. In one preferred embodiment, the ancillary electrical component is a capacitor. In a preferred embodiment, a terminal is provided on the semiconductor device such that the capacitor can be electrically connected directly to the terminals, as by soldering or with conductive epoxy. Connecting the capacitor between terminals of a power loop provides superior noise and transient suppression. The very short path between the capacitor and the active circuit provides for extremely low inductance, allowing for the use of relatively small capacitors. The semiconductor device then is connected to an electronic device such as a PC board for further connection to other circuitry. One particularly preferred mode of connection is by incorporating resilient, free-standing contact structures on the same semiconductor device, with the structures standing farther away from the semiconductor and the capacitor. Other useful connectors include providing similar resilient, free-standing contact structures on the other device, then positioning the semiconductor over the resilient contacts and securing the two devices together. A socket with such resilient structures is particularly useful for this application. In an alternative preferred embodiment, the capacitor and resilient contacts all are incorporated in the second device, such as a socket. In one aspect of the invention, the ancillary electrical component may include a travel stop structure which defines a minimum separation between the semiconductor and a substrate such as a printed circuit board.

Abstract: A semiconduct chip assembly includes a chip, terminals permanently electrically connected to the chip by flexible leads and a resilient element or elements for biasing the terminals away from the chip. The chip is permanently engaged with a substrate having contact pads so that the terminals are disposed between the chip and the substrate and the terminals engage the contact pads under the influence of the force applied by the resilient element. The terminals typically are provided on a flexible sheet-like dielectric interposer and the resilient element is disposed between the interposer and the chip. The assembly of the chip and the terminals can be tested prior to engagement with the substrate. Because engagement of this assembly with the substrate does not involve soldering or other complex bonding processes, it is reliable. The assembly can be extremely compact and may occupy an area only slightly larger than the area of the chip itself.
