    摘要: In a semiconductor circuit device fabricating process in which a reduction image projection exposure apparatus and an electron beam exposure apparatus are in a mixed use in its exposure process, pattern position shift errors for each exposure apparatus are measured and corrected at the time of drawing by means of an electron beam drawing apparatus, thereby enhancing the alignment accuracy.
    First, a pattern for measuring position shifts is exposed using a stepper and the electron beam drawing apparatus. Then, the position shift errors are measured using an identical coordinate position measuring device. Accidental errors have been mixed in the measurement result at this time. On account of this, measurement data at a certain point are smoothed by taking a summation average with data on the periphery thereof, thus decreasing influences of the accidental errors. Moreover, by inverting positive or negative signs of the data on the position shift errors, the data are made into correction data. Then, the correction data are stored. When an exposure is performed by the electron beam drawing apparatus with the pattern exposed by the stepper as a reference, the correction data for the two apparatuses are transferred to the electron beam drawing apparatus, the two data are added to detected mark positions, and at positions after the addition, pattern position shifts within a wafer surface are determined. At the time of exposure, the exposure is performed at positions obtained by subtracting the correction data from the determined pattern position shifts. This method makes it possible to correct both position shift errors within the wafer surface due to the stepper and position shift errors due to the electron beam drawing apparatus, thus allowing the alignment accuracy to be enhanced. Also, this result makes it possible to enhance yield for products in the fabricating process.

    摘要: The invention discloses a method to easily determine the parameters of a second process for manufacturing from the parameters of a first process. Metrics representative of the differences between the two processes are computed from a number of values of the parameters, which can be measured for the two processes on a calibration layout, or which can be determined from pre-existing values for layouts or reference data for the two processes by an interpolation/extrapolation procedure. The number of metrics is selected so that their combination gives a precise representation of the differences between the two processes in all areas of a design. Advantageously, the metrics are calculated as a product of convolution of the target design and a compound of a kernel function and a deformation function.

    摘要: A lithographic apparatus includes an illumination system configured to condition a radiation beam, a support for a patterning device, a substrate table for a substrate, a projection system, and a control system. The patterning device is capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam. The projection system is configured to project the patterned radiation beam as an image onto a target portion of the substrate along a scan path. The scan path is defined by a trajectory in a scanning direction of an exposure field of the lithographic apparatus. The control system is coupled to the support, the substrate table and the projection system for controlling an action of the support, the substrate table and the projection system, respectively. The control system is configured to correct a local distortion of the image in a region along the scan path by a temporal adjustment of the image in that region, thereby reducing the intra-field overlay errors.
