## Company history

Tower Semiconductor was founded in 1993 after acquiring National Semiconductor’s 150-mm fabrication facility in Migdal Haemek, Israel. Its expansion included the start of operations at a second Migdal Haemek fab in 2003 and, in 2008, a merger with Jazz Technologies that added Jazz Semiconductor’s Newport Beach facility. [18](https://app.finbar.com/go?id=P153224357)[27](https://app.finbar.com/go?id=P153224501)[28](https://app.finbar.com/go?id=P153224130)

The company expanded in Japan in 2014 by acquiring a 51% stake in TPSCo, which brought three factories into its manufacturing network, and in 2016 acquired Fab 9 in San Antonio from Maxim. In 2024, its Fab 10 facility in Agrate, Italy, completed qualification and began volume production. Tower discontinued operations at its original Fab 1 in 2025, consolidating some production into Fab 2. In March 2026, Tower and Nuvoton agreed to divide ownership of two TPSCo fabs, subject to approvals and closing conditions.
