INTEGRATED SEMICONDUCTOR CIRCUIT HAVING AN INTERCONNECTION LAYER CONSISTING OF AN ALUMINIUM/SILICON ALLOY

摘要

Contact interconnect levels for integrated circuit with a semiconductor substrate consisting of silicon in which and on which components forming the circuit are produced, are composed essentially of an aluminum/silicon/titanium alloy having a proportion of about 1 through 2% by weight silicon and a titanium content of less than about 0.5% by weight. The reliability and loadability of electrical interconnects for VLSI systems is increased by utilization of this metallization.
