  • Publication number: 20240085803
    Abstract: Photolithography overlay errors are a source of patterning defects, which contribute to low wafer yield. An interconnect formation process that employs a patterning photolithography/etch process with self-aligned interconnects is disclosed herein. The interconnection formation process, among other things, improves a photolithography overlay (OVL) margin since alignment is accomplished on a wider pattern. In addition, the patterning photolithography/etch process supports multi-metal gap fill and low-k dielectric formation with voids.
