A great observation RL, my first thought is it's just a matter of financial resources available to set up the mini LWLG fab, compared to the virtually unlimited budget of a UAE owned GF fab. I would tend to think it's just a matter of increasing the recipe ratios of the Perk to accommodate the 300mm wafers?
I don't claim to have any insight of the difference in cost between the equipment needed to produce 100mm vs 300mm wafers, but my guess would be it's like shopping for a Hyundai vs a Lamborghini...;)
