Microelectronic workpieces that have bump sites over bond-pads and methods of fabricating such bump sites. One embodiment of such a workpiece, for example, includes a substrate having a plurality of microelectronic dies comprising integrated circuitry and bond-pads, such as copper bond-pads, electrically coupled to the integrated circuitry. The workpiece further includes (a) a dielectric structure having a plurality of openings with sidewalls projecting from corresponding bond-pads, and (b) a plurality of caps over corresponding bond-pads. The individual caps can include a discrete portion of a barrier layer attached to the bond-pads and the sidewalls of the openings, and a discrete portion of a cap layer on the barrier layer. The caps are electrically isolated from each other and self-aligned with corresponding bond-pads without forming a mask layer over the cap layer.

An MRAM device having a plurality of MRAM cells formed of a fixed magnetic layer, a second soft magnetic layer and a dielectric layer interposed between the fixed magnetic layer and the soft magnetic layer. The MRAM cells are all formed simultaneously and at least some of the MRAM cells are designed to function as antifuse devices whereby the application of a selected electrical potential can short the antifuse device to thereby affect the functionality of the MRAM device.

The invention encompasses an electrical apparatus. Such apparatus comprises a first substrate having first circuitry thereon. The first circuitry has a terminal extending therefrom, and the terminal defines a first electrical node. The apparatus further comprises a first dielectric material covering a predominate portion of the first circuitry and not covering the first electrical node. Additionally, the apparatus comprises a second substrate having second circuitry thereon. The second circuitry has a terminal extending therefrom, and such terminal defines a second electrical node. A second dielectric material covers a predominate portion of the second circuitry, but does not cover the second electrical node. The second substrate comprises a different material than the first substrate. A portion of the second substrate is over a portion of the first substrate to define an overlap between the first and second substrates. The second electrical node overlaps the first electrical node in the overlap between the first and second substrates. A conductive material is within the overlap between the first and second substrates and electrically bonds the first and second electrical nodes to one another. The invention also encompasses termite sensing devices, methods of forming electrical apparatuses, and methods of sensing termites.
