Abstract
Disclosed herein is a method of cutting one or more kinds of quadrangular unit pieces having a relatively small size from a quadrangular base material having a relatively large size using a cutter frame including a plurality of cutters to manufacture the quadrangular unit pieces, the method including (a) an inspection step of scanning a quadrangular base material in a longitudinal direction and in a lateral direction of the quadrangular base material to check positions of defects on the quadrangular base material, (b) a calculation step of calculating a yield when imaginarily cutting the quadrangular base material using two or more kinds of cutting frames, (c) a selection step of selecting one of the cutting frames in which the yield calculated at the calculation step (b) is within a range of upper 30%, and (d) a manufacturing step of cutting the quadrangular base material using the cutting frame selected at the selection step (c) to manufacture quadrangular unit pieces.
