 customer demand, we discontinued the lower-margin legacy 150mm process flows, ceased operations in Fab 1 and consolidated certain strategic flows into Fab 2, also located in Migdal Haemek, Israel, in order to streamline our production processes and enhance our overall efficiency.
 

In 2003, we commenced production at Fab 2, a wafer fabrication facility we established in Migdal Haemek, Israel. Fab 2 supports geometries ranging from 0.35 to 0.13-micron, utilizing advanced CMOS technology, including CMOS image sensors, matrix ionizing radiation sensors, devices employing metamaterials, embedded flash, advanced analog, RF (radio frequency), specifically RF switches on SOI, power platforms and mixed-signal technologies.
 
In September 2008, we merged with Tower NPB, which holds 100% of NPB Co. and operates Fab 3, located in Newport Beach, California, U.S. Fab 3 specializes in specialty process technologies of silicon photonics, analog and mixed-signal semiconductor devices, and supports geometries ranging from 0.50 to 0.13-micron. NPB Co.’s specialty process technologies support applications requiring advanced analog, radio frequency, high voltage, bipolar, SOI and silicon germanium bipolar, complementary metal oxide (“SiGe”) and silicon photonics processes. Fab 3 wafers are used by our customers for a wide range of products, including devices for high-speed data, communications, cellular phones, wireless local area networking devices, digital TVs, set-top boxes, gaming devices, switches, routers and broadband modems.
 
In March 2014, we acquired from Panasonic 51% of a newly established company, TPSCo, that became a foundry for the sale of wafers to Panasonic and other third-party customers, using three factories established by Panasonic in Hokuriku Japan (Uozu E, Tonami CD and Arai E). Pursuant to the transaction, Panasonic transferred its capacity tools (8 inch and 12 inch) at these three fabs to TPSCo. TPSCo focuses on 65nm and 180nm geometries for RF, power management and CMOS image senor wafers, products and applications. In July 2022, the operations in Japan were reorganized and restructured such that the Arai factory, which solely served NTCJ and did not serve Tower or TPSCo foundry customers, ceased operations. The operations at the
