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.

Some embodiments include methods of forming interconnects through semiconductor substrates. An opening may be formed to extend partway through a semiconductor substrate, and part of an interconnect may be formed within the opening. Another opening may be formed to extend from a second side of the substrate to the first part of the interconnect, and another part of the interconnect may be formed within such opening. Some embodiments include semiconductor constructions having a first part of a through-substrate interconnect extending partially through a semiconductor substrate from a first side of the substrate; and having a second part of the through-substrate interconnect extending from a second side of the substrate and having multiple separate electrically conductive fingers that all extend to the first part of the interconnect.

The present invention relates to a process for realizing a connecting structure (2200) in a semiconductor substrate (1000), and the semiconductor substrate realized accordingly. The process of the present invention, the semiconductor substrate (1000) having at least a first surface, and being foreseen for a 3D integration with a second substrate (1700) along the first surface, wherein the 3D integration is subject to a lateral misalignment in at least one dimension having a misalignment value, can include the step of growing a diffusion barrier structure (2211) for preventing diffusion of elements out of a conductive layer into the rest of the semiconductor substrate, is characterized in that a first end surface, being the most outward surface of the diffusion barrier structure (2211) being substantially parallel to the first surface, along a direction perpendicular to the first surface and going from the substrate toward the first surface, of the diffusion barrier structure (2211) can have a length, in the direction of the lateral misalignment, the length being dependent on the misalignment value, wherein the length of the diffusion barrier structure (2211) is chosen such that in a 3D integrated structure a diffusion of elements out of a conductive layer of the second substrate (1700) is prevented in the integrated state.

摘要:
An interconnect structure having an incomplete via opening is processed to deepen a via opening and to expose a metal line. In case the interconnect structure comprises a metal pad or a blanket metal layer, the metal pad or the metal layer is removed selective to an underlying dielectric layer to expose the incomplete via opening. Another dielectric layer is formed within the incomplete via opening to compensated for differences in the total dielectric thickness above the metal line relative to an optimal dielectric stack. A photoresist is applied thereupon and patterned. An anisotropic etch process for formation of a normal via opening may be employed with no or minimal modification to form a proper via opening and to expose the metal line. A metal pad is formed upon the metal line so that electrical contact is provided between the metal pad and the metal line.
