Abstract
Dielectric helmet-based approaches for back end of line (BEOL) interconnect fabrication, and the resulting structures, are described. In an example, a semiconductor structure includes a substrate. A plurality of alternating first and second conductive line types is disposed along a same direction of a back end of line (BEOL) metallization layer disposed in an inter-layer dielectric (ILD) layer disposed above the substrate. A dielectric layer is disposed on an uppermost surface of the first conductive line types but not along sidewalls of the first conductive line types, and is disposed along sidewalls of the second conductive line types but not on an uppermost surface of the second conductive line types.
