Abstract:
A method of forming an overlay mark includes disposing a first feature of a plurality of first alignment segments extending along a first direction in a first layer, disposing a second feature of a plurality of second alignment segments extending along a second direction in a second layer over the first layer, and forming a third feature of a plurality of third alignment segments extending along the first direction and a plurality of fourth alignment segments extending along the second direction in a third layer over the second layer. In a plan view, each first alignment segment of the first alignment segments is adjacent to a corresponding third alignment segment of the third alignment segments along the first direction, and each second alignment segment of the second alignment segments is adjacent to a corresponding fourth alignment segment of the fourth alignment segments along the second direction.

Claim (Index 18):
The method of  claim 15 , wherein measuring the first deviation between the fourth alignment segments and the second alignment segments comprises:\n detecting an intensity I 1  of a positive first order diffraction on gratings of the fourth alignment segments and the second alignment segments; detecting an intensity I 2  of a negative first order diffraction on gratings of the fourth alignment segments and the second alignment segments; and calculating an intensity difference of I 1  and I 2  on gratings of the fourth alignment segments and the second alignment segments, wherein the first deviation is proportional to the intensity difference.
