Abstract:
1. A method of controlling a semiconductor dicing saw, comprising: dynamically adjusting a saw cut pattern of the semiconductor dicing saw during a sawing operation of at least a portion of a semiconductor wafer based on detection of a saw blade of the dicing saw contacting the semiconductor wafer; wherein dynamically adjusting comprises: terminating a current saw cut of the semiconductor dicing saw based upon detection that the saw blade no longer contacts the semiconductor wafer; and proceeding to a subsequent saw cut upon termination of the current saw cut; and wherein terminating a current saw cut comprises: detecting that the saw blade no longer contacts the semiconductor wafer; waiting a predefined time and/or distance of travel of the saw blade after it is detected that the saw blade no longer contacts the semiconductor wafer; and terminating the current saw cut if after the predefined time and/or distance the saw blade still no longer contacts the semiconductor wafer.
