摘要:
The present disclosure relates to an integrated chip structure. The integrated chip structure includes a substrate. One or more lower interconnects are disposed within a lower inter-level dielectric (ILD) structure over the substrate. A plasma induced damage (PID) mitigation layer is disposed over the lower ILD structure. The PID mitigation layer has a porous structure including a metal. A first upper interconnect is laterally surrounded by an upper ILD structure over the PID mitigation layer. The first upper interconnect extends from over the PID mitigation layer to the one or more lower interconnects.
