摘要： A metal hardmask for use with a Dual Damascene process used in the manufacturing of semiconductor devices. The metal hardmask has advantageous translucent characteristics to facilitate alignment between levels while fabricating a semiconductor device and avoids the formation of metal oxide residue deposits. The metal hardmask comprises a first or primary layer of TiN (titanium nitride) and a second or capping layer of TaN (tantalum nitride).

摘要： An interconnect structure in the back end of the line of an integrated circuit forms contacts between successive layers by removing material in the top surface of the lower interconnect in a cone-shaped aperture, the removal process extending through the liner of the upper aperture, and depositing a second liner extending down into the cone-shaped aperture, thereby increasing the mechanical strength of the contact, which then enhance the overall reliability of the integrated circuit.

摘要： The present invention relates to methods for post-etch, particularly post-RIE, removal of fluorocarbon-based residues from a hybrid dielectric structure. The hybrid dielectric structure contains a first dielectric material, and a line-level dielectric layer containing a second, different dielectric material, and wherein said second, different dielectric material comprises a polymeric thermoset dielectric material having a dielectric constant less than 4. Low energy electron beam or low temperature annealing is utilized by the present invention for removal of the fluorocarbon-based residues from such a hybrid dielectric structure, without damaging the low-k polymeric thermoset dielectric material contained in such a hybrid dielectric structure.
