    Abstract: A computer-implemented method includes executing, using a computer, a process including a main thread that receives a layout file. The layout file includes a first plurality of tags and compressed information blocks. Each tag of the first plurality is associated with a compressed information block. The method further includes decompressing the compressed information blocks using sub-threads and thereby obtaining decompressed information blocks. The sub-threads are created by the main thread, and each sub-thread corresponds to a compressed information block. The decompressed information blocks are combined into decompressed layout information. The decompressed file is partitioned and each partition is provided to a node of a distributed computing system for performing layout correction. Multiple result files each in a compressed format are obtained from the distributed computing system and the result files are combined to obtain a single result file without decompressing and re-compressing the results from the distributed computing system.

    Abstract: Systems and methods are provided for generating test patterns. In various embodiments, systems and methods are provided in which machine learning is utilized to generate the test patterns in a manner so that the test patterns conform with design rule check (DRC) specified for a particular semiconductor manufacturing process or for particular types of devices. A test pattern generation system includes test pattern generation circuitry which receives a noise image. The test pattern generation generates a pattern image based on the noise image, and further generates a test pattern based on the pattern image. The test pattern is representative of geometric shapes of an electronic device design layout that is free of design rule check violations.

    Abstract: Disclosed is a method of fabricating an integrated circuit (IC) using a multiple (N>2) patterning technique. The method provides a layout of the IC having a set of IC features. The method further includes deriving a graph from the layout, the graph having vertices connected by edges, the vertices representing the IC features, and the edges representing spacing between the IC features. The method further includes selecting vertices, wherein the selected vertices are not directly connected by an edge, and share at least one neighboring vertex that is connected by N edges. The method further includes using a computerized IC tool to merge the selected vertices, thereby reducing a number of edges connecting the neighboring vertex to be below N. The method further includes removing a portion of the vertices that are connected by less than N edges.

    Abstract: The present disclosure describes a method for forming metal interconnects in an integrated circuit (IC). The method includes placing a metal interconnect in a layout area, determining a location of a redundant portion of the metal interconnect, and reducing, at the location, the length of the metal interconnect by a length of the redundant portion to form one or more active portions of the metal interconnect. The length of the redundant portion is a function of a distance between adjacent gate structures of the IC. The method further includes forming the one or more active portions on an interlayer dielectric (ILD) layer of the IC and forming vias on the one or more active portions, wherein the vias are positioned about 3 nm to about 5 nm away from an end of the one or more active portions.
