AN INTERCONNECT COMPONENT FOR A SEMICONDUCTOR DIE INCLUDING A RUTHENIUM LAYER AND A METHOD FOR ITS FABRICATION

摘要

A multi-layered metal bond pad for a semiconductor die having a conductive metal layer and an overlying ruthenium electrode layer. The ruthenium electrode layer protects the conductive metal from oxidation due to ambient environmental conditions. An interconnect structure such as a wire bond or solder ball may be attached to the ruthenium layer to connect the semiconductor die to a lead frame or circuit support structure. Also disclosed are processes for forming the ruthenium layer.
