摘要:
Selective area deposition of metal films by atomic layer deposition (ALD) and chemical vapor deposition (CVD) is described. In an example, a method of fabricating a metallization structure for an integrated circuit involves forming an exposed surface above a substrate, the exposed surface including regions of exposed dielectric material and regions of exposed metal. The method also involves forming, using a selective metal deposition process, a metal layer on the regions of exposed metal without forming the metal layer on the regions of exposed dielectric material.

摘要:
Methods of forming cobalt films utilizing a cobalt precursor comprising an additive are described. Those methods may include adding an additive to a cobalt precursor, wherein the cobalt precursor is located in an ampoule that is coupled with a deposition tool, and then forming a cobalt film using the cobalt precursor comprising the additive. Non-volatile decomposition products of the cobalt precursor are solubilized in the ampoule.

Techniques are disclosed for forming through-silicon vias (TSVs) implementing a negative thermal expansion (NTE) material such as zirconium tungstate (ZrW2O8) or hafnium tungstate (HfW2O8). In some cases, the NTE material is disposed between the substrate and conductive core material of the TSV and serves to offset, at least in part, the coefficient of thermal expansion (CTE) mismatch there between, thus reducing heat-induced stresses and/or protrusion (pumping) of the conductive core material. The NTE material also may protect against leakage, voltage breakdown, and/or diffusion of the conductive core material. Furthermore, the NTE material may reduce radial stresses in high-aspect-ratio TSVs. In some cases, techniques disclosed herein may improve TSV reliability, enhance three-dimensional integration, and/or enhance performance in three-dimensional integrated circuits and/or other three-dimensional packages. Other embodiments which can employ techniques described herein will be apparent in light of this disclosure.

The present invention provides a process for the production of a glycol via tandem self condensation of formaldehyde via formoin condensation and transfer hydrogenation of the reaction products of the formoin condensation. In some aspects, synthetic processes of the present invention utilize a combination of a N-heterocyclic carbene catalyst and a transition metal hydrogen-transfer catalyst providing enhanced selectivity and increased yields for the production of ethylene glycol relative to conventional synthetic approaches based on formoin condensation.

Embodiments of the present disclosure describe a selective diffusion barrier between metals of an integrated circuit (IC) device and associated techniques and configurations. In one embodiment, an apparatus includes a dielectric material, a first interconnect structure comprising a first metal disposed in the dielectric material, a second interconnect structure comprising a second metal disposed in the dielectric material and electrically coupled with the first interconnect structure and a diffusion barrier disposed at an interface between the first interconnect structure and the second interconnect structure, wherein the first metal and the second metal have a different chemical composition, material of the diffusion barrier and the second metal have a different chemical composition and material of the diffusion barrier is not disposed directly between the second metal and the dielectric material. Other embodiments may be described and/or claimed.
