摘要： A hardmask layer in the back end of an integrated circuit is formed from TaN having a composition of less than 50% Ta and a resistivity greater than 400 μOhm-cm, so that it is substantially transparent in the visible and permits visual alignment of upper and lower alignment marks through the hardmask and intervening layer(s) of ILD. A preferred method of formation of the hardmask is by sputter deposition of Ta in an ambient containing N2 and a flow rate such that (N2 flow)/(N2+carrier flow)>0.5.

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.

摘要： An interconnect structure in which the adhesion between an upper level low-k dielectric material, such as a material comprising elements of Si, C, O, and H, and an underlying diffusion capping dielectric, such as a material comprising elements of C, Si, N and H, is improved by incorporating an adhesion transition layer between the two dielectric layers. The presence of the adhesion transition layer between the upper level low-k dielectric and the diffusion barrier capping dielectric can reduce the chance of delamination of the interconnect structure during the packaging process. The adhesion transition layer provided herein includes a lower SiOx- or SiON-containing region and an upper C graded region. Methods of forming such a structure, in particularly the adhesion transition layer, are also provided.

摘要： A damascene wire and method of forming the wire. The method including: forming a mask layer on a top surface of a dielectric layer; forming an opening in the mask layer; forming a trench in the dielectric layer where the dielectric layer is not protected by the mask layer; recessing the sidewalls of the trench under the mask layer; forming a conformal conductive liner on all exposed surface of the trench and the mask layer; filling the trench with a core electrical conductor; removing portions of the conductive liner extending above the top surface of the dielectric layer and removing the mask layer; and forming a conductive cap on a top surface of the core conductor. The structure includes a core conductor clad in a conductive liner and a conductive capping layer in contact with the top surface of the core conductor that is not covered by the conductive liner.
