The new so-called Fab 24-2 is the most technologically advanced, high-volume semiconductor manufacturing plant in the world building multi-core microprocessors, claimed Intel.

The Leixlip, Ireland-based fab is Europe’s first and Intel’s third 65-nanometer chip factory in high production, according to Intel. The chipmaker has similar facilities in the US, in Arizona and Oregon.

Fab 24-4 will initially be used to make dual-core processors based on the company’s new low-power Core microarchitecture.

Our manufacturing capability is key to fueling Intel’s success, said Intel chief executive Paul Otellini, in a statement.

The new facility means Intel currently is producing more than half of its PC and server microprocessors using the 65-nm manufacturing node.

During the next few months, Intel is set to launch new processors based on its Core microarchitecture, including its desktop and notebook version called Core2 Duo (formerly Conroe and Merom), and its server processor called Dual-Core Intel Xeon processor 5100 series (formerly Woodcrest).
