Intel has announced it will invest between $6bn (£3.8bn) and $8bn (£5bn) in new manufacturing plants in the US for the next generation of miniaturised silicon chips.
The announcement comes a year after Intel committed $7bn in investment to chip-making plants in the US to build faster, smaller, energy efficient chips.
The chip maker said it will build a new fabrication plant in Oregon and upgrade four existing factories in Arizona and Oregon, according to the Financial Times.
The plants will produce chips with 22nm-wide circuits, 10nm smaller than the current generation.
Intel said the investment will create up to 8,000 construction jobs and result in up to 1,000 new permanent high-tech jobs.
"Today's announcement reflects the next tranche of the continued advancement of Moore's Law and a further commitment to invest in the future of Intel and America," said Intel chief executive Paul Otellini.
Moore's Law states that the number of transistors that can incorporated into chips will double every two years.
The first 22nm chips are expected to go into production at the end of 2011 and appear in products in 2012.
