Chipping wafer
WebPhotos 1 and 2 show backside chipping in a 25 µm-thick silicon wafer, the backside of which was dry polished prior to dicing. For the workpiece in Photo 1, a #2000 blade was employed, typical for standard-thickness dicing; backside chipping, however, is substantial. For the workpiece in Photo 2, a #4800 blade (much finer grit) was employed ... Web2 days ago · The tipster goes on to clarify that FoWLP tech allows for the manufacturer to skip using a printed circuit board (PCB), resulting in thinner semiconductors with higher performance, as the chip is mounted straight to the silicon wafers. If we follow the logic here, this should translate to better device performance with higher power efficiency.
