    • PURPOSE: A method and apparatus for measuring an overlay are provided to generate a correction signal by performing an inverse Fourier transform of a second spectrum signal generated by filtering a first spectrum signal. CONSTITUTION: An original signal is generated by using a first overlay measurement key and a second overlay measurement key(S110). A first spectrum signal is generated by performing a Fourier transform of the original signal(S120). A second spectrum signal is generated by filtering the first spectrum signal(S130). A correction signal is generated by performing the inverse Fourier transform of the second spectrum signal(S140).
