Abstract(in English) | We have found voids in gold line of GaAs IC under high temperature DC bias test. The voids moved toward a cathode, in the opposite direction of electron flow. The velocity of a cathode edge is larger than that of an anode edge, bringing expansion of the void. The velocity of voids increased with the current density almost proportionally. The moving mechanisms of a void can be explained by assuming that gold atoms move toward an anode by electromigration. The activation energy of the void velocity was 0.84 eV at the cathode side. The GaAs IC failed at the almost same time as the voids appeared. The activation energy of MTF(mean time to failure)of the IC was 0.89 eV, which was nearly equal to that of the void velocity at the cathode edge of 0.84 eV. |
