TSEM

Tower Semiconductor Ltd.

A maker of specialty microchips, Tower Semiconductor runs "foundry" factories that manufacture analog and mixed-signal chips designed by other companies — the silicon inside everything from smartphone image sensors to power-management and radio-frequency gear. Founded in 1993 in Migdal Haemek, Israel, it grew out of a chip plant National Semiconductor had operated and took the name "Tower" from that facility. After merging with California's Jazz Semiconductor in 2008, it briefly called itself TowerJazz before returning to the Tower name in 2020.
