Patent ID: 7168352

Claim:
A process for sawing a substrate strip having a plurality of substrate areas by a saw machine, and the process comprising the steps of: providing a plurality of alignment marks around each individual substrate area on the substrate strip; providing a plurality of cutting marks around each individual substrate area on the substrate strip; positioning the saw machine with respect to each individual substrate area in accordance with the alignment marks there around; cutting each individual substrate area on the substrate strip by the saw machine respectively according to cutting tracks defined by the cutting marks; wherein the substrate strip has a longitudinal axis and a lateral axis and the substrate areas are disposed along the longitudinal axis, the saw machine is positioned with respect to a first substrate area according to the alignment marks along the longitudinal axial from one side thereof and cuts the substrate strip according to cutting tracks defined by the cutting marks parallel to the lateral axis; repositioning the saw machine with respect to an adjacent one of the substrate areas after the substrate strip undergoes shrinkage; and cutting the substrate strip, wherein cutting error that results from each substrate area will not accumulate to the subsequent substrate areas in the substrate strip.
