Stealth laser dicing process

WebThus, Stealth Dicing™ process contributes to producing narrower streets. It is expected to increase the number of die yielded from each wafer compared to the conventional dicing process. Die Strength Improvement In conventional blade dicing, front and backside chipping and processing marks remaining on the side wall can affect die strength. WebFeb 8, 2024 · The laser can also be focused to deliver this heat into the bulk of the wafer, this method is called “stealth” laser dicing. For this approach, the heat from the laser creates voids within the dicing lane. These weakened regions then act like a perforation and tear apart when the wafer is expanded.
