Intel has said that the company will invest between $6bn and $8bn on future generations of manufacturing technology in its American facilities.

The multi-billion investment will fund deployment of its 22- nanometer (nm) manufacturing process across existing US factories, and construction of a new development fabrication plant in Oregon.

The company said that the first 22nm microprocessors, codenamed ‘Ivy Bridge’ will be in production in late 2011 which will increase the levels of performance and power efficiency.

The upgraded fabs will create the capacity for the continued growth of the PC market segment and additional computing markets Intel is addressing including mobile and embedded computing.

Intel said that the new capital expenditure follows it’s previous investment announced in February 2009 which resulted in 32nm process technology.

The new investment in advanced semiconductor manufacturing will create 6,000 to 8,000 construction jobs and 800 to 1,000 new permanent high-tech jobs.

Intel said that the new development fab in Oregon to be called ‘D1X’ is scheduled for R&D startup in 2013 while upgrades are also planned for a total of four existing factories in Arizona (known as Fab 12 and Fab 32) and Oregon (known as D1C and D1D).
