Self-confined metallic interconnects for very large scale integration

Abstract

A novel method to produce narrow metallic lines is presented. Lines of NiSi2 lithographically formed on SiO2 substrates are oxidized. The formed SiO2 layer consumes most of the Si from the silicide, leaving a metallic Ni line fully confined by SiO2. The associated problems together with the potential utilization are discussed.
