Seems reasonable, semi is fabbed with a lithographic process, the # of devices on the wafer isn’t necessarily tightly coupled with size, has variable resolution and defects.

The work unit is completed wafers that later get binned into different device quality levels.

Makes sense when your biz is to blast plasma over mm2 of silicon

What you're saying seems to make sense if they were referring to output in terms of total area of substrates produced, but instead sounds like TFA is talking about manufacturing floor space

You're right, I didn't pick up on that, thank you.

Does it really? I for one certainly did a double-take at the GP's interpretation. It's a product that's usually measured in surface area, and was reported in surface area. Feels pretty obviously related to the product itself, not the factory floor.
