Abstract: Model-Based Sub-Resolution Assist Feature (SRAF) generation process and apparatus are disclosed, in which an SRAF guidance map (SGM) is iteratively optimized to finally output an optimized set of SRAFs as a result of enhanced signal strength obtained by iterations involving SRAF polygons and SGM image. SRAFs generated in a prior round of iteration are incorporated in a mask layout to generate a subsequent set of SRAFs. The iterative process is terminated when a set of SRAF accommodates a desired process window or when a predefined process window criterion is satisfied. Various cost functions, representing various lithographic responses, may be predefined for the optimization process.

Abstract: The present invention relates to a method of selecting a subset of patterns from a design, to a method of performing source and mask optimization, and to a computer program product for performing the method of selecting a subset of patterns from a design. According to certain aspects, the present invention enables coverage of the full design while lowering the computation cost by intelligently selecting a subset of patterns from a design in which the design or a modification of the design is configured to be imaged onto a substrate via a lithographic process. The method of selecting the subset of patterns from a design includes identifying a set of patterns from the design related to the predefined representation of the design. By selecting the subset of patterns according to the method, the selected subset of patterns constitutes a similar predefined representation of the design as the set of patterns.

Abstract: The present invention provides a method of SNP detection by using DASH technique in bead-based microfluidics comprising following steps: (a) immobilizing a target single-strand DNA onto a microbead; (b) hybridizing the target single-strand DNA with an allele-specific probe; (c) intercalating a dye into a target-probe duplex region; (d) delivering the microbead into a microchannel; (e) heating the microbead to denature a hybridized DNA obtained from the step (c); (f) monitoring a fluorescence intensity of the hybridized DNA during the step (e) to obtain a melting curve; and (g) determining the SNP by a melting curve analysis method. Also, the present invention offers a rapid genotyping detection scheme with minimal amount of the reagents by confining the microbeads into designed fluidic traps and performing melting curve analysis controlled by a temperature control platform. The trapping mechanism was validated and optimized.

Abstract: The method of the invention tracks how the collective movement of edge segments in a mask layout alters the resist image values at control points in the layout and simultaneously determines a correction amount for each edge segment in the layout. A multisolver matrix that represents the collective effect of movements of each edge segment in the mask layout is used to simultaneously determine the correction amount for each edge segment in the mask layout.

Abstract: A multivariable solver for proximity correction uses a Jacobian matrix to approximate effects of perturbations of segment locations in successive iterations of a design loop. The problem is formulated as a constrained minimization problem with box, linear equality, and linear inequality constraints. To improve computational efficiency, non-local interactions are ignored, which results in a sparse Jacobian matrix.

Abstract: A drawer cart with in-mold labels includes a cart and a plurality of drawers made by injection molding. Each drawer has a housing compartment opened upward and a display surface. The drawers are slidably mounted onto the cart with the display surfaces exposed outwards and can be partially drawn away from the cart to expose the housing compartment. The display surface contains an in-mold label formed during the injection molding. The in-mold label has patterns for indication and visual aesthetic, and also facilitating classification of goods held in the drawers. The patterns on the in-mold label can be designed differently in response to varying display surfaces and can be combined to form a whole pattern to enhance total design sense and meet use requirements.
