    Abstract: A method includes etching a portion of a wafer to form a first trench in a scribe line of the wafer, wherein the scribe line is between a first device die and a second device die of the wafer. After the etching, a top surface of the portion of wafer in the scribe line is underlying and exposed to the first trench, and the first trench is between opposing sidewalls of the wafer. A laser grooving process is then performed to form a second trench extending from the top surface further down into the wafer, and the second trench is laterally between the opposing sidewalls of the wafer. A die-saw process is then performed to saw the wafer. The die-saw process is performed from a bottom of the second trench, and the die-saw process results in the first device die to be separated from the second device die.
