Abstract: In various embodiments, the present disclosure provides capacitors and methods of forming capacitors. In one embodiment, a capacitor includes a substrate, a first electrode on the substrate, a second electrode, and a first dielectric layer. A portion of the first electrode is exposed in a contact region. The first dielectric layer includes a first dielectric region between the first electrode and the second electrode, and a second dielectric region between the first dielectric region and the contact region. The second dielectric region is contiguous to the first dielectric region, and a surface of the second dielectric region defines a surface path between the first electrode and the contact region. The second dielectric region has a plurality of grooves that increase a spatial extension of said surface path.
