    摘要: A management apparatus which manages a parameter for an industrial device acquires AGA measurement results obtained by operating the industrial device with an operation job parameter value and non-operation job parameter value. An inspection apparatus acquires an nullinspection resultnull obtained by inspecting the result of operating the industrial device in the operation job. A change in inspection result upon a change in parameter value is estimated on the basis of the AGA measurement result and inspection result. A variable which minimizes (extreme) both or at least one of the sensitivity (slope) of the inspection result upon a change in parameter value and variations (3 null) in inspection result between objects to be processed (e.g., wafers) is set as an optimal parameter.

    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 (4) 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 (4) optimizes alignment processing on the basis of the AGA measurement results, alignment parameter, and actually measured exposure position.

    摘要: This invention provides a computer apparatus which is connected to an exposure apparatus capable of executing AGA measurement by using a set parameter value and another parameter value and executing acquisition processing of acquiring measurement results, and an overlay inspection apparatus for inspecting the processing result obtained with the set parameter value in the exposure apparatus, and which executes optimization processing of optimizing the set parameter value on the basis of the processing results acquired in acquisition processing and the inspection result value by the inspection apparatus. The computer apparatus causes the inspection apparatus to acquire and accumulate inspection result values, and evaluates variations in processing results on the basis of the accumulated inspection results. Based on the evaluation result, the computer apparatus decides a frequency at which acquisition processing in the semiconductor exposure apparatus is executed. While a decrease in volume production throughput is prevented during volume production by the industrial device, the parameter value can be optimized during volume production.

    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 industrial 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 industrial device can be properly reflected in another industrial device, realizing efficient parameter value setting.

    摘要: A position detector suitable for an exposure apparatus includes a reticle stage on which is provided a reticle-stage reference mark constituted by a substrate that exhibits a transmitting property with respect to alignment light. In alignment measurement, the relative position of the reticle-stage reference mark and a wafer alignment mark is detected. The relative position of a reticle reference mark and reticle alignment mark is measured beforehand using a separate detection mechanism, and the relative position of a reticle and wafer is decided from the relative position of the reticle-stage reference mark and wafer alignment mark.
