Pretty much any facility capable of manufacturing semiconductor components has been very busy for the past few years -- Intel even had to resurrect 22nm chips at some time. Why do you assume that this will "go out of fashion in 5 years"? Historically this seems extremely unlikely. If anything, tens of millions of people going out of poverty every year are going to be consuming even more chips.

And every year 80+ million people come of age such that they become electronics consumers, buying smartphones, laptops and so on. A billion new electronics consumers every ~12 years. The world is going to need a lot more chip manufacturing capacity over the next few decades.
