The company manufactures specialty analog integrated circuits for semiconductor companies such as: On Semiconductor, Intel,[6] Broadcom, Panasonic, Teledyne, Samsung, Skyworks Solutions, Semtech and Vishay – Siliconix. Moreover, the company also has Qualified open foundry Silicon Photonics platform which is used by companies such as Inphi Corporation.[7] Tower Semiconductor operates seven manufacturing facilities: Fab 1 and Fab 2 (150mm and 200mm) located in Migdal Haemek, Israel, Fab 3 and Fab 9 (200 mm) located in Newport Beach, California and in San Antonio, Texas, two additional fabs (200 mm and 300 mm) through TPSCo located in the Hokuriku region of Japan, and is sharing a 300 mm manufacturing facility being established in Italy with ST Microelectronics. In addition, Tower Semiconductor operates a worldwide design center in Netanya, Israel.

Tower Semiconductor is an Israeli public company that is traded on NASDAQ and the Tel Aviv Stock Exchange, both under the ticker TSEM, and is included in the TA-35 Index and the TA BlueTech Index. In 2010, Tower Semiconductor became the #1 specialty foundry by revenue, with 70% revenue growth year-over-year.[8]

Tower Semiconductor was founded in 1993, with the acquisition of National Semiconductor’s 150mm wafer fabrication facility in Migdal Haemek, Israel. Tower became a public company in 1994 and shares are traded on NASDAQ (TSEM) and Tel Aviv Stock Exchange (TSEM). In January 2001, an adjacent facility (Fab 2) was constructed.

In September 2008, Tower acquired Jazz Semiconductor in a stock for stock transaction. In November 2009, the combined companies officially launched as TowerJazz.

In June 2011, TowerJazz acquired Micron Technology's fabrication facility in Nishiwaki City, Hyogo, Japan. The acquisition nearly doubled TowerJazz's 2010 internal manufacturing capacity and cost-effectively increased production by 60,000 wafers per month.

In April 2014, TowerJazz announced the successful transaction with Panasonic Corporation (First Section of TSE and NSE ticker: 6752) to form a newly established Japanese company, TowerJazz Panasonic Semiconductor Co. (TPSCo) for the manufacture of Panasonic and additional third-party products. TowerJazz announced cessation of its Nishiwaki facility operations in the course of rationalizing and restructuring its manufacturing and business activities in Japan. This enables the company to reduce its annual fixed costs by approximately $130 million per annum.

In February 2016, TowerJazz announced the successful acquisition of an 8-inch wafer fabrication facility in San Antonio, Texas, United States from Maxim Integrated Products, Inc., the consideration, of $40 million was paid by approximately 3.3 million ordinary TowerJazz shares. This acquisition increased TowerJazz's production by 28,000 wafers per month.

On 21 August 2017, TowerJazz, and Tacoma (Nanjing) Semiconductor Technology Co., Ltd announced that TowerJazz received a first payment from Tacoma (Nanjing) according to their agreement for establishing a partnership to build a wafer fab in China. TowerJazz would provide its technical knowledge and project management skills, meanwhile Tacoma (Nanjing), and a Chinese regional authorities named Nanjing Economic and Technology Development Zone, would fully support and fund the project.[9][10] On 22 June 2020, the Chinese court announced that Tacoma (Nanjing) Semiconductor Technology Co., Ltd was in bankruptcy proceedings.[11]

On March 1, 2020, TowerJazz announced a new brand identity. As of March 2020, the company's official brand name is Tower Semiconductor and includes all of the company's worldwide subsidiaries.[12]

On February 15, 2022, Intel announced an agreement to acquire Tower Semiconductor for $5.4 billion.[13][14] On August 16, 2023, Intel terminated the acquisition as it failed to obtain approval from Chinese regulators within the 18-month transaction deadline period and will pay a termination fee of $353 million to Tower.[15][16]

Tower Semiconductor offers[19] a broad range of advanced analog process technologies. The company's analog technology offerings include: SiGe BiCMOS, Silicon Photonics, and RF CMOS (SOI and bulk) for radio frequency (RF) and high performance analog (HPA) applications; CMOS image sensor (CIS); non-imaging sensors, power management, including 700 V BCD; CMOS; mixed-signal CMOS and MEMS capabilities. Tower Semiconductor's modular and customizable processes are available on either 150 mm, 200 mm or 300 mm wafers in its seven fabrication facilities.
