  • Patent number: 12353123
    Abstract: A semiconductor manufacturing apparatus and a semiconductor manufacturing method thereof are provided. Wafers are grouped into a first wafer group and a second wafer group according to alignment mark position errors of the wafers and a first threshold value. The alignment mark position errors of the first wafer group are greater than the first threshold value, and the alignment mark position errors of the second wafer group are less than or equal to the first threshold value. A feedforward position correction value is calculated according to a difference between the alignment mark position errors of the first wafer group and a reference error value. A lithography process is performed on the wafers according to the feedforward position correction value.
