Abstract
A method of sorting laminates includes characterizing first shapes of laminates from measurements taken of each, assembling the laminates to derive a first relationship between the first shapes and yield loss, characterizing second shapes of the laminates from a reduced number of the measurements to derive a second relationship between the second shapes and yield loss, analyzing a change in the derived relationships to determine a least number of the measurements necessary for achieving the yield loss and sorting supplied laminates in accordance with a characterized shape of each, which is obtained from the least number of the measurements taken for each supplied laminate.
