1. A wafer sawing method for sawing a wafer by using a cutting tool, a surface of the wafer comprising a plurality of sawing paths, the wafer sawing method comprising:
providing a carrier whose dimension is greater than a dimension of the wafer, having at least a fiducial mark being formed on the carrier;
forming a plurality of strip-shaped adhesives on the carrier, corresponding to the plurlaity of sawing paths on the surface of the wafer;
bonding the wafer to the carrier, wherein the surface of the wafer comrpising the plurlaity of sawing paths faces the carrier, and the fiducial mark is disposed outside a bonding region between the wafer and the carrier, wherein the plurality of strip-shaped adhesives within the bonding region is bonded to the plurlaity of sawing paths on the surface of the wafer;
positioning the cutting tool and the carrier according to the fiducial mark; and
sawing the wafer by using the cutting too.
