  • Patent number: 9087739
    Abstract: Improved fidelity to an integrated circuit pattern design in a semiconductor structure ultimately produced is achieved by modeling material removal and deposition processes in regard to materials, reactant, feature size, feature density, process parameters and the like as well as the effects of such parameters on etch and material deposition bias due to microloading and RIE lag (including inverse RIE lag) and using the models to work backward through the intended manufacturing method steps, including hard mask pattern decomposition, to morphologically develop feature patterns for use in most or all process steps which will result in the desired feature sizes and shapes at the completion of the overall process. Modeling of processes may be simplified through use of process assist features to locally adjust rates of material deposition and removal.

  • Publication number: 20100042967
    Abstract: A method that purposely relaxes OPC algorithm constraints to allow post OPC mask shapes to elongate along one direction (particularly lowering the 1-dimensional MEEF in this direction with the result of an effectively overall lowered MEEF) to produce a pattern on wafer that is circular to within an acceptable tolerance.

  • Patent number: 7402532
    Abstract: 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.

  • Patent number: 7211507
    Abstract: 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.
