I didn't mean they aren't, but said not as much as TSMC. TSMC has already announced US, Japan new Fabs and China fab expension. They are also discussing with Germany and India govt.

Because Samsung's Foundry are not as mature and profitable as TSMC. You dont built Foundry and expect customer to come. You wait until your customer confirm their orders years in advance before you stamp that $20B cost in building a new fab.
