FYI: The cost of building the fab is already a significant percentage of the cost of building chips.
"The increase in cost and complexity is encapsulated in Rock's Law, which dictates that fab construction costs double every four years. That law is itself tightly connected to the better-known Moore's Law, which dictates that the number of transistors on a chip doubles every two years."

"By 2007, the price of building a fab is expected to reach $6 billion."

$6 billion * 2 ^ 10 = 6 trillion in 20 years.
