Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor structure comprising:
a first dielectric layer comprising a first conductive metal feature embedded in the first dielectric layer;
a second dielectric layer comprising a second conductive metal feature embedded in the second dielectric layer, wherein the second dielectric layer comprises a uniform composition throughout, wherein the second conductive metal feature is above and directly contacts the first conductive metal feature, wherein a sidewall of the second dielectric layer comprises a first repeating series of convex curves, and wherein a sidewall of the second conductive metal feature comprises a second repeating series of convex curves; and
an interface between the second conductive metal feature and the second dielectric layer is where the first repeating series of convex curves contact the second repeating series of convex curves.
