Why even make the final giant chip rectangular? I get that the exposure reticles are rectangular, but since this is tiling a bunch of connected chiplets, why no

Why even make the final giant chip rectangular? I get that the exposure reticles are rectangular, but since this is tiling a bunch of connected chiplets, why not use the full area of the wafer?
- petra 7y agoYou need to make sure you're io lines are imprinted on the edge of the wafer. It's much easier to do by making the io lines at the ends of each "chip" , vs a circle that cuts in the middle of the "chip".
