US semiconductor business M/A-COM Tech is creating 30 jobs at its international headquarters in Cork city.

M/A-Com Tech already employs 68 staff there.

After setting up in Ireland in 2008, the company started an IDA supported research and development project in integrated circuit design.

The new positions will see jobs in engineering, supply chain, quality and administration.

''The establishment of its research and development centre is in keeping with IDA Ireland's focus on attracting increased investment to Ireland in R&D which has the added benefit of making companies more strategically important to their parent corporations while embedding existing employment,'' commented IDA Ireland's chief executive Barry O'Leary.

Meanwhile, five European firms - Culture Translate, Diaceutics, Nimble Apps, iMosphere and Unique Digital - are setting up operations in Ireland, with a combined 77 jobs for Limerick, Dundalk and Dublin.
