发明名称 Big via structure
摘要 A semiconductor device that includes a first metal layer component formed over a substrate. The semiconductor device includes a via formed over the first metal layer component. The via has a recessed shape. The semiconductor device includes a second metal layer component formed over the via. The semiconductor device includes a first dielectric layer component formed over the substrate. The first dielectric layer component is located adjacent to, and partially over, the first metal layer component. The first dielectric layer component contains fluorine. The semiconductor device includes a second dielectric layer component formed over the first dielectric layer component. The first dielectric layer component and the second dielectric layer component are each located adjacent to the via. The second dielectric layer component is free of fluorine.
