  • Patent number: 8689176
    Abstract: A computer implemented method, system, and/or computer program product modifies a master template for an executable document. A version architecture comprises a master template for a master document, a new variation document that describes what changes are to be made to the master template for a specific context, and a resulting modified template based on the master template and rule-based instructions found in the new variation document. A processor defines an executable master document from the master template that, when executed, produces a final product. Specific rules set out conditions for modifying the master template for the specific context. These specific rules are used to define a new variation document, which is applied against the master template to generate a context-specific modified template. The context-specific modified template is then used to generate a context-specific executable document that, when executed, generates a final context-specific product.

  • Publication number: 20130339970
    Abstract: A computer implemented method, system and/or computer program product schedules execution of work requests through work plan prioritization. One or more work packets are mapped to and assigned to each work request from a group of work requests. A complexity level is derived for and assigned to each work packet, and priority levels of various work requests are determined for each entity from a group of entities. A global priority for the group of work requests is then determined. The global priority and the complexity levels combine to create a priority function, which is used to schedule execution of the work requests.

    Abstract: A method for illuminating a mask to project a desired image pattern into a photoactive material is described. The method includes receiving an image pattern. Determining a relationship between source pixels in a set of source pixels to desired intensities at one or more points in the image pattern is performed. Linear constraints are imposed on a set of intensity values based on one or more contingent intensity condition. The contingent intensity conditions include integer variables specifying contingent constraints. The method includes determining values of the set of intensity values in accordance with the linear constraints, using a constrained optimization algorithm. The set of intensity values represents intensities of a set of source pixels. The set of intensity values are output. Apparatus and computer readable storage media are also described.

  • Publication number: 20130263150
    Abstract: A computer implemented method, system and/or computer program product automatically allocates resources to functional areas of an enterprise activity environment. A skill level of a resource is determined for multiple functional areas. An affinity index is created and associated with each of the multiple functional areas, wherein the affinity index is based on a level of productivity drop of other resources in a specific functional area if the resource is assigned to another functional area. Expected resource and skill level requirements of a project are identified. The resource is automatically allocated to one or more functional areas based on the affinity index associated with a particular functional area in view of the expected resource and skill level requirements.

  • Patent number: 8495528
    Abstract: A simplified version of a multiexpose mask optimization problem is solved in order to find a compressed space in which to search for the solution to the full problem formulation. The simplification is to reduce the full problem to an unconstrained formulation. The full problem of minimizing dark region intensity while maintaining intensity above threshold at each bright point can be converted to the unconstrained problem of minimizing average dark region intensity per unit of average intensity in the bright regions. The extrema solutions to the simplified problem can be obtained for each source. This set of extrema solutions is then assessed to determine which features are predominantly printed by which source. A minimal set of extrema solutions serves as a space of reduced dimensionality within which to maximize the primary objective under constraints. The space typically has reduced dimensionality through selection of highest quality extrema solutions.

  • Patent number: 8453076
    Abstract: Optical wave data for a semiconductor device design is divided into regions. First wavefront engineering is performed on the wave data of each region, accounting for just the wave data of each region and not accounting for the wave data of neighboring regions of each region. The optical wave data of each region is normalized based on results of the first wavefront engineering. Second wavefront engineering is performed on the wave data of each region, based at least on the wave data of each region as has been normalized. The second wavefront engineering takes into account the wave data of each region and a guard band around each region that includes the wave data of the neighboring regions of each region. The second wavefront engineering can be sequentially performed by organizing the regions into groups, and sequentially performing the second wavefront engineering on the regions of each group in parallel.

  • Patent number: 8407073
    Abstract: Each work item from a group of work items is categorized as either complex or intense, and a unique work requirement statement is derived for each work item based on whether it is complex or intense. A unique resource value statement is assigned to different human resources. Past performances of the human resources are analyzed against completed work items in order to adjust the unique resource value statement, thus creating updated human resource value statements. An optimized work requirement statement is created by recalculating the unique work requirement statement for each work item based on the updated human resource value statements. A schedule for automated allocation of human resources to functional areas of an enterprise activity environment and scheduling of work items to the functional areas is formulated based on the optimized requirement statement for each work item in the group of work items.

  • Patent number: 8351037
    Abstract: Programmable illuminators in exposure tools are employed to increase the degree of freedom in tool matching. A tool matching methodology is provided that utilizes the fine adjustment of the individual source pixel intensity based on a linear programming (LP) problem subjected to user-specific constraints to minimize the difference of the lithographic wafer data between two tools. The lithographic data can be critical dimension differences from multiple targets and multiple process conditions. This LP problem can be modified to include a binary variable for matching sources using multi-scan exposure. The method can be applied to scenarios that the reference tool is a physical tool or a virtual ideal tool. In addition, this method can match different lithography systems, each including a tool and a mask.
