A next-generation semiconductor research and development, and manufacturing facility is being built.
Taoiseach Leo Varadkar has been welcoming the news;
“This is a really significant announcement for Limerick and the Mid-West region, which marks a new chapter in the longstanding relationship between ADI and Ireland.
"This massive €630 million investment is great news for local employment with lots of jobs being created during the construction phase, and 600 high-end graduate jobs.
"Most IDA jobs created in recent years have been outside of Dublin, and Limerick has done particularly well with its deep talent pool, universities, airport, and infrastructure."
He added that such a significant investment will also have a knock-on effect;
"This investment will also mean lots of spin-off jobs and contracts for local SMEs and Irish-owned businesses.
