Bonded wafer grinding or ultrathin grinding may cause edge chipping which is one of the critical issues leading to wafer breakage. Chipping may be induced by the rounded profile of the wafer's outer edges. The edge trimming process eliminates the rounded profile of the outer edge ensuring edge strength and chipping decrease.
