Stealth Definition & Meaning - Merriam-Webster

WebIn the SD method, stealth dicing is performed from the ground back surface after the back grinding (BG) process. In contrast to conventional dicing where the chips are completely separated during blade dicing (BD), the SD method allows the individual chips to be still integrated with the wafer even after stealth dicing. WebMar 2, 2024 · In this approach, rather than performing a cutting or stealth dicing process from the front side 1 of the wafer W, the wafer W is subjected to stealth dicing from the back side 6 thereof. In particular, a pulsed laser beam is applied to the wafer W from its back side 6, as is indicated by arrows in FIG. 12.
