Alignment Method for Linear-Scale Projection Lithography Based on CCD Image Analysis
This paper presents a method to improve the alignment accuracy of a mask in linear scale projection lithography, in which the adjacent pixel gray square variance method is applied to a charge-coupled device (CCD) image to obtain the best position of the focal length of the motherboard and then reali...
