20130015350 | Electron-Beam Image ReconstructionAANM Chen; DongxueAACI Palo AltoAAST CAAACO USAAGP Chen; Dongxue Palo Alto CA USAANM Hu; ChangqingAACI SunnyvaleAAST CAAACO USAAGP Hu; Changqing Sunnyvale CA USAANM Pang; LinyongAACI Los GatosAAST CAAACO USAAGP Pang; Linyong Los Gatos CA US - A technique for reconstructing an electron-beam (EB) image, which can be a scanning-electron-microscope (SEM) image or an EB-inspection image, is described. This reconstruction technique may involve an inverse electro-optical calculation that corrects for the influence of an electro-optical transfer function associated with an EB system on the EB image. In particular, in the inverse calculation a multi-valued representation of an initial EB image is at an image plane in the model of the electro-optical transfer function and a resulting EB image is at an object plane in the model of the electro-optical transfer function. Furthermore, the model of the electro-optical transfer function may have an analytical derivative and/or may be represented by a closed-form expression. | 01-17-2013 |
20130139116 | LITHOGRAPHICALLY ENHANCED EDGE DETERMINATION - During a calculation technique, at least a portion of a target pattern associated with an integrated-circuit design is modified so that polygons in the target pattern, which represent features in the design, result in acceptable accuracy during a photolithographic process that fabricates the target pattern on a semiconductor die. In particular, a set of polygon parameters associated with the polygons are modified, as needed, so that a cost function that corresponds to a difference between a modified target pattern and an estimated target pattern produced during the photolithographic process meets a termination criterion. A mask pattern that can fabricate the modified target pattern on the semiconductor die is calculated using an inverse optical calculation in which the modified target pattern is at an image plane of an optical path associated with the photolithographic process and the mask pattern is at an object plane of the optical path. | 05-30-2013 |
20140278231 | Film-Growth Model Using Level Sets - A technique for determining a set of surface profiles in a multilayer stack during a fabrication process may be determined using a model of this fabrication process, a geometry of the multilayer stack (such as a pre-defined geometry of the multilayer stack) and a surface profile in the multilayer stack (such as a measured surface profile of the top surface or a bottom surface of the multilayer stack). For example, the model of the fabrication process may be based on a generalized Eikonal equation. In conjunction with deposition rates and/or physical properties of the layers in the multilayer stack, deposition or growth of the multilayer stack may be simulated. Based on the determined set of surface profiles, an acceptance condition of the multilayer stack (such as a multilayer stack in a photo-mask for use in extreme ultra-violet photolithography) may be determined and/or a remedial action may be recommended. | 09-18-2014 |

20100236823 | RING OF POWER VIA - Systems and methods for providing plated through-holes (PTH) in PCBs, which advantageously allow improved soldering capabilities, are described herein. Such systems and methods are achieved by reducing the heat sinking effects of PTHs by providing one or more vias surrounding the PTHs to provide an electrical connection between the PTH and the internal and bottom conductive layers of a PCB. In this regard, the PTHs are spaced apart from at least one of the internal conductive layers (e.g., ground or power layers), so the heat sinking effects are reduced. This feature enables molten solder to substantially fill the entire PTH before freezing, thereby improving the mechanical and electrical connection between an electrical component and the PCB. | 09-23-2010 |
