    摘要: A method and an apparatus are provided to measure a position of a mark with a less measurement error caused by a variation in a wafer process condition. The mark is illuminated with light and an image of the mark is formed, via an optical system, in a light receiving surface of a sensor. The image of the mark is sensed and image data thereof is acquired by the sensor. Correction data of a fundamental harmonic and a high harmonic of the image data is set based on information associated with a shape of the mark, an imaging magnification of the optical system, and an area of the sensor. The image data is corrected using the correction data, and the position of the mark is calculated using the corrected image data.

    摘要: An exposure apparatus performs AGA measurement by using a predetermined sample shot group formed on a wafer, and decides an alignment parameter. The exposure apparatus executes wafer alignment processing and exposure processing by using the alignment parameter. The exposure apparatus notifies a central processing unit of AGA measurement results and the alignment parameter. An overlay inspection apparatus measures an actual exposure position on the exposed wafer, and notifies the central processing unit of the measurement result. The central processing unit optimizes alignment processing on the basis of the AGA measurement results, alignment parameter, and actually measured exposure position.

    摘要: A system which manages a plurality of semiconductor exposure apparatuses holds TIS information representing the characteristics of the respective semiconductor exposure apparatuses. In a semiconductor exposure apparatus, a parameter value is optimized on the basis of AGA measurement results obtained using a set parameter value and another parameter value and AGA measurement estimation results obtained by virtually changing the parameter value. Whether to reflect the optimized parameter value in another exposure device is decided on the basis of the TIS information. If it is decided to reflect the optimized parameter value, the parameter value of another semiconductor exposure apparatus is optimized by the optimized parameter value. In this manner, the optimization result of a parameter value by a given exposure device can be properly reflected in another exposure device, realizing efficient parameter value setting.
