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

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.
