  • Method and apparatus for localizing weak points within an electrical circuit
    Patent number: 4640626
    Abstract: A method and apparatus localize weak points within an electrical circuit. The electrical circuit is covered with a liquid crystal and is heated to a temperature just below the clearing point of the liquid crystal. The liquid crystal converts into its unordered condition given a temperature increase and leakage channel within the integrated circuit are completely localized. By irradiating a three-dimensional region, at least one current is induced in the region by generating electron-hole pairs within the electrical circuit, this at least one current causing a temperature increase at at least one weak point of the electrical circuit.
