Technology giant Intel picked the Republic of Ireland to design its next major chip processor line -- rating the country ahead of keen competition from Israel, Malaysia and the US.
It is the first time that a major product from a global technology company has been designed in the country.
"All our Christmases and birthdays rolled into one when our CEO announced it," said Philip Moynagh, Intel's general manager for the processor in Kildare.
The chip, called Quark, which has already been made on a limited basis, goes into mass production next month.
It carries the words "designed in Ireland" on it. "Those three words are very exciting for us here. We couldn't be more proud," added Mr Moynagh.
The chip will power everyday items, from wearable technology such as smart watches to air conditioners.
The announcement came as figures revealed US firms invested $130bn (€95bn) in the Republic between 2008 and 2012 -- 14 times more than the US investment in China.
