Re: Shortages

If you double the die size, the number of chips per wafer will be less than 50% of what it was before.

Imperfections per wafer will be much the same as before, and will likely affect about the same number of chips per wafer as before, but that would be a higher proportion of the total.

To give an extreme example, if yield per wafer was previously 50%, if you double the chip size, then the yield could fall to almost 0%.
