If yield rates aren't a good metric, what does he think is then? It's certainly not layoff numbers, or C-suite compensation.
If after all that investment you're only able to produce TEN PERCENT of the product successfully, that's a failure, by definition. Even if they quintuple the yields, that's still incredibly poor
Yield over die area should be the metric.
If you have a chip that is 50% of the wafer area, a single fault will lead to a yield of 50%. Now compare it with a chip that is 1% of the wafer area, the same single fault gets a yield of 99%.
So comparing the yields of two processes without factoring in the die area is not a fair game.
