    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.

    摘要: One embodiment of the present invention concerns an integrated circuit that includes bond pads and special contact pads or points. The bond pads are for interfacing the integrated circuit as a whole with an external circuit, and are to be bonded to a package or circuit board. The bond pads are disposed on the die in a predetermined alignment such as a peripheral, grid, or lead-on-center alignment. The special contact pads are used to provide external test patterns to internal circuits and/or to externally monitor results from testing the internal circuits. The special contact pads may be advantageously located on the integrated circuit with a high degree of positional freedom. For one embodiment, the special contact pads may be disposed on the die at a location that is not in the same alignment as the bond pads. The special contact pads may be smaller than the bond pads so as not to increase the die size due to the special contact pads. The special contact points may also be used to externally program internal circuits (e.g., nonvolatile circuits) at the die or package level. The special contact points may also be used to select redundant circuits for faulty circuits.
