Abstract:
1. A semiconductor construction, comprising: a first electrically conductive structure over a semiconductor substrate, the first electrically conductive structure having a lateral periphery; a second electrically conductive structure over the semiconductor substrate and surrounding an entirety of the lateral periphery of the first electrically conductive structure; the second electrically conductive structure having an outer lateral edge; a ring of electrically insulative material between the first and second electrically conductive structures; a planar horizontal surface extending along the first electrically conductive structure, the second electrically conductive structure and the ring of electrically insulative material; and a segment of nickel-containing material along the planar horizontal surface and in direct contact with the first and second electrically conductive structures and with the ring of electrically insulative material; the segment of nickel-containing material having an outer lateral edge; a planar vertical surface extending along the outer lateral edges of the nickel-containing material and the second electrically conductive structure.
