A call-management method and system for distributing calls to agents, wherein each agent has a profile, e.g., defining agent skills, efficiency, etc. The call center management system implements an algorithm for selecting an agent to receive a call to optimize caller utility, call center efficiency, and agent training. Therefore, the algorithm does not seek to necessarily route a call to the agent having the skill set most suited to the call; rather, the call may be routed to an agent who needs experience in the area of the call, and thus serves as a training exercise. Skilled agents may be made available to shadow the training agent when available.

Agent training sensitive call routing system

A semiconductor device includes a substrate and a number of diffusion regions defined within the substrate. The diffusion regions are separated from each other by a non-active region of the substrate. The semiconductor device includes a number of linear gate electrode tracks defined to extend over the substrate in a single common direction. Each linear gate electrode track is defined by one or more linear gate electrode segments. Each linear gate electrode track that extends over both a diffusion region and a non-active region of the substrate is defined to minimize a separation distance between ends of adjacent linear gate electrode segments within the linear gate electrode track, while ensuring adequate electrical isolation between the adjacent linear gate electrode segments.

Phase information is incorporated into a cell-based design methodology Standard cells have four edges: top, bottom, left, and right The top and bottom edges have fixed phase shifters placed, eg 0 A given cell C will have a phase set created with two versions: 0-180 (left-right) as well as 180-0 Alternatively, the same phase set: 0—0 and 180—180 could be created for a cell The phase sets are selected based on the ability to phase shift the features within the cell C By creating a phase set for most of the cells of a cell library, standard cell placement and routing techniques can be used and phase can then be quickly assigned using a simple ripple technique This ensures a phase compliant design upfront for the standard cell areas In some instances, phase sets are created for every cell in a library

Standard cell design incorporating phase information

A method of generating patterns of a pair of photomasks from a data set defining a circuit layout to be provided on a substrate includes identifying critical segments of the circuit layout to be provided on the substrate. Block mask patterns are generated and then legalized based on the identified critical segments. Thereafter, phase mask patterns are generated, legalized and colored. The legalized block mask patterns and the legalized phase mask patterns that have been colored define features of a block mask and an alternating phase shift mask, respectively, for use in a dual exposure method for patterning features in a resist layer of a substrate.

Generating mask patterns for alternating phase-shift mask lithography

Definition of a phase shifting layout from an original layout can be time consuming. If the original layout is divided into useful groups, i.e. clusters that can be independently processed, then the phase shifting process can be performed more rapidly. If the shapes on the layout are enlarged, then the overlapping shapes can be grouped together to identify shapes that should be processed together. For large layouts, growing and grouping the shapes can be time consuming. Therefore, an approach that uses bins can speed up the clustering process, thereby allowing the phase shifting to be performed in parallel on multiple computers. Additional efficiencies result if identical clusters are identified and processing time saved so that repeated clusters of shapes only undergo the computationally expensive phase shifter placement and assignment process a single time.

Design data format and hierarchy management for processing

Techniques are provided for extending the use of phase shift techniques to implementation of masks used for complex layouts in the layers of integrated circuits, beyond selected critical dimension features. The method includes identifying features for which phase shifting can be applied, automatically mapping the phase shifting regions for implementation of such features, resolving phase conflicts which might occur according to a given design rule, and application of assist features and proximity correction features. The method includes applying an adjustment to a phase shift mask pattern including a first and a second phase shift window, and a control chrome with a control width, and/or to a trim mask pattern having a trim shape with a trim width based upon one or both of a rule based correction and a model based correction to improve a match between a resulting exposure pattern and a target feature.
