摘要： Fail sites in a semiconductor are isolated through a difference image of a fail area and a healthy area. The fail area comprises an image of a semiconductor with a fail. The healthy area comprises an image of a semiconductor absent the fail or, in other words, an image of a semiconductor with healthy structure. Instructions cause a variation in the intensities of the difference image to appear at the fail site.

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： Methods of depositing a tantalum-nitride (TaN) diffusion barrier region on low-k materials. The methods include forming a protective layer on the low-k material substrate by performing plasma-enhanced atomic layer deposition (PE-ALD) from tantalum-based precursor and a nitrogen plasma in a chamber. The protective layer has a nitrogen content greater than its tantalum content. A substantially stoichiometric tantalum-nitride layer is then formed by performing PE-ALD from the tantalum-based precursor and a plasma including hydrogen and nitrogen. The invention also includes the tantalum-nitride diffusion barrier region so formed. In one embodiment, the metal precursor includes tantalum penta-chloride (TaCl5). The invention generates a sharp interface between low-k materials and liner materials.

摘要： Prevention of damage to an interlevel dielectric (ILD) is provided by forming an opening (e.g., trench) in the ILD, and sputtering a dielectric film onto a sidewall of the opening by overetching into a layer of the dielectric below or within the ILD during forming of the opening. The re-sputtered film protects the sidewall of the opening from subsequent plasma/ash processes and seals the porous dielectric surface along the sidewall and bottom without impacting overall process throughput. A semiconductor structure resulting from the above process is also disclosed.
