Abstract
A method for reducing stripe patterns comprising receiving scattered light signals from a backside surface of a laser annealed backside illuminated image sensor wafer, generating a backside surface image based upon the scattered light signals, determining a distance between an edge of a sensor array of the laser anneal backside illuminated image sensor wafer and an adjacent boundary of a laser beam and re-calibrating the laser beam if the distance is less than a predetermined value.
