Abstract
A capacitor structure that includes a substrate; a conductive layer above the substrate; and a porous layer, above the conductive layer, having pores that extend perpendicularly from a top surface of the porous layer toward the conductive layer. The porous layer comprises a first region in which pores conductive wires are disposed, and a second region in which pores a metal-insulator-metal (MIM) structure is disposed. The first region may be used as a via to contact a bottom electrode of the capacitor structure.
