Abstract
Aluminum thin films were electrically stressed in a high‐vacuum furnace and the damage resulting from the electromigration of aluminum ions was monitored by the change in stripe resistance. When high‐purity oxygen was periodically bled into the furnace, ranged between a constant value and zero, depending on the magnitude of ΔR. The proposed model suggests the stabilization of microscopic voids by the formation of a thin oxide film on the void surface.
