    Abstract: An interconnect structure employs a closed-grid bus to link an integrated circuit tester channel to an array of input/output (I/O) pads on a semiconductor wafer so that the tester channel can concurrently communicate with all of the I/O pads. The interconnect structure includes a circuit board implementing an array of bus nodes, each corresponding to a separate one of the I/O pads. The circuit board includes at least two layers. Traces mounted on a first layer form a set of first daisy-chain buses, each linking all bus nodes of a separate row of the bus node array. Traces mounted on a second circuit board layer form a set of second daisy-chain buses, each linking all bus nodes of a separate column of the bus node array. Vias and other circuit board interconnect ends of the first and second daisy-chain buses so that they form the closed-grid bus. Each bus node is connected though a separate isolation resistor to a separate contact pad mounted on a surface of the circuit board. A set of spring contacts or probes link each contact pad to a separate one of the I/O pads on the wafer.

    Abstract: A planarizer for a probe card assembly. A planarizer includes a first control member extending from a substrate in a probe card assembly. The first control member extends through at least one substrate in the probe card assembly and is accessible from an exposed side of an exterior substrate in the probe card assembly. Actuating the first control member causes a deflection of the substrate connected to the first control member.

    Abstract: An image of an array of probes is searched for alignment features. The alignment features are then used to bring contact targets and the probes into contact with one another. The alignment features may be a feature of one or more of the tips of the probes. For example, such a feature may be a corner of one of the tips. An array of probes may be formed to have such alignment features.

    Abstract: 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.

    Abstract: A semiconductor wafer is cut to singulate integrated circuit dice formed on the wafer. A die pick machine then positions and orients the singulated dice on a carrier base such that signal, power and ground pads formed on the surface of each die reside at predetermined positions relative to landmarks on the carrier base the die pick machine optically identifies. With the dice temporarily held in place on the carrier base, they are subjected to a series of testing and other processing steps. Since each die's signal pads reside in predetermined locations, they can be accessed by appropriately arranged probes providing test equipment with signal access to the pads during tests. After each test, a die pick machine may replace any die that fails the test with another die, thereby improving efficiency of subsequent testing and other processing resources.
