Latest Patents

Eric C. Chang holds a patent titled "Method of maintaining signal integrity across a capacitive coupled solder bump." This invention presents a novel method and computer program product that utilizes an interface capacitor formed by the metal of the probe tip, a dielectric layer, such as an oxide, formed by a contaminant on a solder bump, and the metal of the solder bump. The interface capacitor forms a capacitive divider with the inherent capacitances of the automatic test equipment and the device under test (DUT). The voltage characteristics of the capacitive divider are used to drive voltage signals across the interface capacitor to test the DUT. This method allows for valid testing of the DUT even if all I/O bumps have an oxide layer.
