Israel’s foundry specialist built a business around analogue chips rather than the smallest nodes
Tower Semiconductor was founded in Israel in 1993 and began operations using a wafer fabrication facility acquired from National Semiconductor.
The company focused on specialty semiconductor processes rather than competing solely for leading-edge digital logic.
The early business looks very different from the company visible today. Following the milestones in order shows which decisions changed Tower Semiconductor’s direction and which capabilities remained constant.
Mixed-signal and analogue processes created a differentiated foundry model
Tower developed manufacturing for RF, power management, image sensors and other applications that require specialised process features.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
Jazz Semiconductor expanded the US footprint
Tower merged with Jazz Technologies in 2008, adding manufacturing capacity and strengthening RF and mixed-signal capabilities.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
Japanese fabs increased global capacity
The company expanded manufacturing through a joint venture with Panasonic’s semiconductor operations in Japan, creating additional specialty-process scale.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
Intel’s failed acquisition left Tower independent
Intel agreed to acquire Tower in 2022, but the deal was terminated in 2023 after regulatory approval did not arrive in time. Tower continued as an independent foundry.
The transaction mattered because it changed the shape of Tower Semiconductor rather than simply adding revenue. It brought additional technology, customers, geographic reach or operating capability into the group and influenced the next stage of its strategy.
Specialty process technology became the foundry’s moat
As of 18 September 2026, tower Semiconductor remains focused on analogue and specialty foundry processes. Its history shows why semiconductor manufacturing is not only a contest to reach the smallest node; many high-value chips depend on processes optimised for radio, power or sensors.
The distance between “Mixed-signal and analogue processes created a differentiated foundry model” and “Intel’s failed acquisition left Tower independent” captures the larger story: Tower Semiconductor kept extending the value of its original expertise into new products, markets or infrastructure.
