The speaker estimates that about 80% of the tool set might be reusable when moving from 18A to 14A, while 14A would require some unique tools for its denser geometry.

“So let's say going from 18A to 14A, maybe you would say 80% of the tool set can be reused. And then of course 14A, for example, would require some new capabilities because it's a, it's a denser geometry, so it would require some unique tools.”
