Publication number: 20240085803Abstract: 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.
