  • Patent number: 8019458
    Abstract: The invention provides a method of processing a wafer using multilayer processing sequences and Multi-Layer/Multi-Input/Multi-Output (MLMIMO) models and libraries that can include one or more measurement procedures, one or more Poly-Etch (P-E) sequences, and one or more metal-gate etch sequences. The MLMIMO process control uses dynamically interacting behavioral modeling between multiple layers and/or multiple process steps. The multiple layers and/or the multiple process steps can be associated with the creation of lines, trenches, vias, spacers, contacts, and gate structures that can be created using isotropic and/or anisotropic etch processes.

  • Publication number: 20110039355
    Abstract: The invention can provide apparatus and methods of processing a substrate using plasma generation by gravity-induced gas-diffusion separation techniques. By adding or using gases including inert and process gases with different gravities (i.e., ratio between the molecular weight of a gaseous constituent and a reference molecular weight), a two-zone or multiple-zone plasma can be formed, in which one kind of gas can be highly constrained near a plasma generation region and another kind of gas can be largely separated from the aforementioned gas due to differential gravity induced diffusion and is constrained more closer to a wafer process region than the aforementioned gas.
