摘要： A plurality of images, including a first image and a second image having a higher resolution than the first image, are aligned by generating an oversampled cross correlation image that corresponds to relative displacements of the first and second images, and, based on the oversampled cross correlation image, determining an offset value that corresponds to a misalignment of the first and second images. The first and second images are aligned to a precision greater than the resolution of the first image, based on the determined offset value. Enhanced results are achieved by performing another iteration of generating an oversampled cross correlation image and determining an offset value for the first and second images. Generating the oversampled cross correlation image may involve generating a cross correlation image that corresponds to relative displacements of the first and second images, and oversampling the cross correlation image to generate the oversampled cross correlation image.

摘要： A method for utilizing interference fringe patterns generated when milling a trench through a semiconductor substrate by a method such as FIB milling, to determine and optimize the thickness uniformity of the trench bottom. The interference fringes may be mapped and the mapping used to direct the FIB milling to those regions which are thicker to correct observed non-uniformities in the trench floor thickness by varying the pixel dwell time across the milled area. The interference fringe mapping may be used to develop computerized contour lines to automate the pixel dwell time variations as described above, for correcting non-uniformities in the trench floor thickness. The method may be applied to applications other than trench formation for backside editing, such as monitoring progress in forming a milled object.
摘要翻译：一种利用通过诸如FIB铣削的方法在通过半导体衬底铣削沟槽时产生的干涉条纹图案的方法，以确定和优化沟槽底部的厚度均匀性。可以映射干涉条纹，并且映射用于将FIB铣削引导到那些较厚的区域，以通过改变铣削区域上的像素停留时间来修正沟槽底板厚度中观察到的不均匀性。如上所述，干涉条纹映射可用于开发计算机化轮廓线以自动化像素驻留时间变化，以校正沟槽底板厚度中的不均匀性。该方法可以应用于除了用于背面编辑的沟槽形成之外的应用，例如监测形成铣削对象的进展情况。

摘要： A method and apparatus for defining a circuit operation, such as a charged particle beam operation to perform a circuit edit and define a probe point. Circuit operation definition is performed in a front-end environment with access to integrated circuit computer aided design tools providing logic level and layout level information concerning the integrated circuit. The front-end environment incorporates circuit operation optimization methods to identify optimal locations for a circuit operation. A back-end environment, such as a charged particle tool computing platform, is adapted to receive one or more files, which may include a truncated layout file with circuit operation location information, for use in further defining a circuit operation and/or performing the circuit operation.

摘要： An apparatus and method for processing an integrated circuit employing optical interference fringes. During processing, one or more wavelength lights are directed on the integrated circuit and based upon the detection of interference fringes and characteristics of the same, further processing may be controlled. One implementation involves charged particle beam processing of an integrated circuit as function of detection and/or characteristics of interference fringes. A charged particle beam trench milling operation is performed in or on the substrate of an integrated circuit. Light is directed on the floor of the trench. Interference fringes may be formed from the constructive or destructive interference between the light reflected from the floor and the light from the circuit structures. Resulting fringes will be a function, in part, of the thickness and/or profile of the trench floor. Milling may be controlled as a function of the detected fringe patterns.

摘要： An apparatus and method for processing an integrated circuit employing optical interference fringes. During processing, light is directed on the integrated circuit and based upon the detection of interference fringes, further processing may be controlled. One implementation involves charged particle beam processing of an integrated circuit as function of detection of interference fringes. A charged particle beam trench milling operation is performed in or on the substrate of an integrated circuit. Light is directed on the floor of the trench. When the floor approaches the underlying circuit structures, some light is reflected from the floor of the trench and some light penetrates the substrate and is reflected off the underlying circuit structures. Interference fringes may be formed from the constructive or destructive interference between the light reflected from the floor and the light from the circuit structures. Processing may be controlled as function of the detection of interference fringes.

摘要： A system, apparatus, and method for analyzing photon emission data to discriminate between photons emitted by transistors and photons emitted by background sources. The analysis involves spatial and/or temporal correlation of photon emissions. After correlation, the analysis may further involve obtaining a likelihood that the correlated photons were emitted by a transistor. After correlation, the analysis may also further involve assigning a weight to individual photon emissions as a function of the correlation. The weight, in some instances, reflecting a likelihood that the photons were emitted by a transistor. The analysis may further involve automatically identifying transistors in a photon emission image.
