Abstract—We report on defects characterization and reduction as well as die strength enhancement using stealth dicing (SD) on high-backside reflectance (82%) 2-D NAND memory wafers. This is performed using three-strata subsurface infrared (1.342 μm) nanosecond pulsed laser die singulation with a partial-SD before grinding integration approach. In this paper, a combination of simulation, cha…
