Patent ID: 7030499

Claim:
A semiconductor construction, comprising: a semiconductor substrate; a stack supported by the semiconductor substrate; the stack comprising an electrically insulative cap over an electrically conductive material; the electrically insulative cap of the stack having a thin central region and a thicker peripheral region, the thin central region joining to the thicker peripheral region at a step; an electrically conductive pillar supported by the semiconductor substrate, the pillar having an uppermost surface and a lateral periphery; an electrically conductive cap on the electrically conductive pillar and having a lateral periphery extending outwardly beyond the lateral periphery of the electrically conductive pillar, the electrically conductive cap and electrically conductive pillar differing in composition relative to one another; at least one first electrically insulative spacer along the step and at least one second electrically insulative spacer along the lateral periphery of the electrically conductive cap; the first and second electrically insulative spacers having the same composition as one another; an electrically insulative material over the stack and over the electrically conductive cap; and an electrical interconnect extending through the electrically insulative material to the electrically conductive material of the stack; the electrical interconnect extending through the thin central region of the electrically insulative cap.
