Semiconductor Constructions, Semiconductor Processing Methods, Methods of Forming Contact Pads, and Methods of Forming Electrical Connections Between Metal-Containing Layers

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;
• and
• a nickel-containing structure over and in direct contact with the first and second electrically conductive structures, the nickel-containing structure including a segment projecting between the first and second electrically conductive structures, the segment being an annulus surrounding the first electrically conductive structure.

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 a first outer lateral periphery;
• a nickel-containing structure over the first and second electrically conductive structures and which extends across the first and second electrically conductive structures, the nickel-containing structure including a segment projecting between the first and second electrically conductive structures and directly contacting the first and second electrically conductive structures, the segment being an polygonal ring surrounding the first electrically conductive structure;
• the nickel-containing structure having a second outer periphery;
• and
• the first and second outer lateral peripheries together forming a substantially vertical sidewall which is entirely directly against an electrically insulative material.
