More Information
Summary:A calibration apparatus is provided. The calibration apparatus includes a wafer carrier configured to support a substrate with a patterned layer. The patterned layer includes a first exposure area and remaining exposure areas, and each of the first and the remaining exposure areas includes a first checking mark. The calibration apparatus also includes a measurement device configured to obtain a first exposure value of the first checking mark of the first exposure area by measuring the first checking mark of the first exposure area. The calibration apparatus also includes a processing module configured to calculate first calculated values of the first checking marks of the remaining exposure areas according to the first exposure value and a standard file. The illumination device is adjusted by an adjustment device of the lithography apparatus according to the first calculated values during a lithography process.
