    摘要: An automated system for analyzing mask defects in a semiconductor manufacturing process is presented. This system combines results from an inspection tool and design layout data from a design data repository corresponding to each mask layer being inspected with a computer program and a predetermined rule set to determine when a defect on a given mask layer has occurred. Mask inspection results include the presence, location and type (clear or opaque) of defects. Ultimately, a determination is made as to whether to scrap, repair or accept a given mask based on whether the defect would be likely to cause product failure. Application of the defect inspection data to the design layout data for each mask layer being inspected prevents otherwise acceptable wafer masks from being scrapped when the identified defects are not in critical areas of the mask.

    摘要: Method for effecting edge bias correction of topography-induced linewidth variations which are encountered in printed or integrated circuits on substrates or semiconductor devices for electronic packages. The method modifies data for current levels which is predicated on prior level data and models, as to the manner in which topography will affect the resist and/or antireflective coating (ARC) thicknesses, so as to improve upon linewidth (LW) control and, in general, imparting improved processing windows. The method can be implemented in the form of computer-executable instructions which are embodied in one or more program modules stored on computer-usable media.

    摘要: A method for including etch bias corrections in pre-processing of integrated circuit design data to compensate for deviations introduced during lithographic printing and etching. The design data is segmented, and etch bias corrections are applied to the segments based on their proximity to adjacent design features. Adjusted or corrected design data is produced which may be used to create a mask which includes etch bias corrections for better fidelity and reproduction of the original design in the etching step. Etch bias corrections may also be applied based upon characteristics of regions defined in the design, or on a pattern density of the design.

    摘要: A structure for a semiconductor chip which includes a first region having first cells for storing and processing data, and a second region outside the first region having OPC structures, wherein the OPC structures comprise decoupling capacitors. The line widths of the active gates of first cells are the same size or similar in size as the OPC structures. The OPC structures reduce proximity effects of active devices in the first cells, and comprise N-type FETs and P-type FETs, that are located in the second region. The OPC structures may have a width greater than the first cells. The second region can be multiple OPC structures, whereby the second region comprises multiple decoupling capacitors. The active devices in the first cells are separated by a first distance and the OPC structures are separated from the active devices by the first distance.
