Abstract:
1. A semiconductor device, comprising: a first metal layer component formed over a substrate; a via formed over the first metal layer component, wherein the via has a first sidewall and an opposing second sidewall such that a recess extends from the first sidewall to the opposing second sidewall; a second metal layer component formed over the via and within the recess; a first dielectric layer component formed over the substrate, wherein the first dielectric layer component is located adjacent to, and partially over, the first metal layer component, and wherein the first dielectric layer component contains fluorine; and a second dielectric layer component formed over the first dielectric layer component, wherein the first dielectric layer component and the second dielectric layer component are each located adjacent to the via, and wherein the second dielectric layer component is free of fluorine.
