Stacked Die Are Coming Soon.
Wang said that for a 100mm² die, yield drops from 500 good chips per wafer at 28nm to 419 at 7nm. For a large, complex 400mm² die, the yield drops from 63 to 31.
In contrast, yields are significantly higher using smaller die packaged together compared with one highly integrated large die.
