  • Publication number: 20070164421
    Abstract: The present invention addresses detection of charge-induced defects through test structures that can be easily incorporated on a wafer to detect charge-induced damage in the back-end-of-line processing of a semiconductor processing line. A test macro is designed to induce an arc from a charge accumulating antenna structure to another charge accumulating antenna structure across parallel plate electrodes. When an arc of a predetermined sufficient strength is present, the macro will experience a voltage breakdown that is measurable as a short. The parallel plate electrodes may both be at the floating potential of the microchip to monitor CMP-induced or lithographic-induced charge failure mechanisms, or have one electrode electrically connected to a ground potential structure to capture charge induced damage, hence having the capability to differentiate between the two.

  • Patent number: 7170090
    Abstract: A test structure and a test methodology are provided for testing metal-insulator-metal (MIM) capacitor structures under high temperatures at the wafer level. The test structure includes a resistor formed on a region of dielectric isolation material formed in a semiconductor substrate. The MIM capacitor is formed over the resistor and separated therefrom by dielectric material. A metal thermometer, formed from the same material as the plates of the MIM capacitor, is placed above the resistor and in close proximity to the capacitor. High current is forced through the resistor, causing both the metal thermometer and the MIM capacitor to heat up along with the resistor. The change in resistance of the metal thermometer is monitored. Using the known temperature coeffecient of resistance (TCR) for the metal used to form both the capacitor and the thermometer, changes in the measured resistance of the metal thermometer are converted to temperature.

  • Patent number: 7161175
    Abstract: The present invention discloses novel methods to transfer data between a plurality of integrated circuit dice on a semiconductor wafer. Each individual die contains internal circuits to control data transfer to nearby dice. Wafer level data transfer is achieved by a series of inter-dice data transfers. It is therefore possible to use a small number of small area metal lines to support wafer level parallel processing activities. External connections are provided by a small number of bonding pads on each wafer. The load on each external bounding pad is by far lower than that of prior art wafer level connections. These inter-dice data transfer mechanism also can be programmed to avoid defective circuitry. This invention has been used to support wafer level functional tests and wafer level burn-in tests. A Testing system of the present invention can test thousands of dice in parallel using simple testing equipment. Testing costs for integrated circuits are therefore reduced dramatically.

Similar testing pads may be provided even with respect to terminals like bonding pads provided with bump electrodes. A probe test is executed by using these testing pads or under the combined use of under bump metallurgies antecedent to the formation of the bump electrodes together with the testing pads. According to the above, bump electrodes for pads dedicated for probe testing may not be added owing to the use of the testing pads. Further, the use of testing pads provided in the neighborhood of the terminals like the bonding pads and smaller in size than the under bump metallurgies enables a probe test to be executed after a relocation wiring process.
