Taiwan Semiconductor Manufacturing Company (TSMC), one of the largest manufacturers of silicon, is seemingly making plans to build as many as six of its US-based fabs in Arizona. According to the unconfirmed report coming from UDN, TSMC could be building its Arizona-based factories for much larger capacities. Based on TSMC's classifications, the MegaFab-class of factories is the one with 25,000 WSPM output. According to the report, TSMC plans to build six additional facilities in the area where the Arizona fab is, and have a GigaFab-class (even larger type) factory present on US soil. Currently, the company operates six GigaFabs and all of them are based in Taiwan.

The GigaFab class factory is supposed to have over 100,000 WSPM output, and by building one in the US, TSMC could get much closer to big customers like Apple, NVIDIA, and AMD. Reports are saying that TSMC's primary target is 3 nm node production on 12-inch (300 mm) wafers. All six of the supposed facilities are expected to output more than 100,000 wafers at their peak, making it one of the largest projects TSMC has ever done. The Arizona location is supposed to serve as a "mega fab" facility and it is supposed to start manufacturing silicon in 2024. This information is, of course, just a rumor so you should take it with a grain of salt, as this type of information is usually only known by top-level management.

In response to incredible customer demand, Intel has doubled its combined 14 nm and 10 nm manufacturing capacity over the past few years. To do this, the company found innovative ways to deliver more output within existing capacity through yield improvement projects and significant investments in capacity expansion. This video recounts that journey, which even included re-purposing existing lab and office space for manufacturing.

"Over the last three years, we have doubled our wafer volume capacity, and that was a significant investment. Moving forward, we're not stopping… We are continuing to invest into factory capacity to ensure we can keep up with the growing needs of our customers," says Keyvan Esfarjani, senior vice president and general manager of Manufacturing and Operations at Intel. The company also ramped its new 10 nm process this year. Intel currently manufactures 10 nm products in high volumes at its Oregon and Arizona sites in the U.S. and its site in Israel.

TSMC plans to open a new 3.5 billion dollar foundry in Arizona with a new wholly-owned US subsidiary. The new foundry will begin construction in 2021 with an expected completion date of 2024. The new facility will target production volumes of 20,000 wafers per month with 5 nm production being the main priority. TSMC will be joining Intel who also produces chips in Arizona enabling them to tap into this well-established supply chain. TSMC plans to employ 1,600 staff at the facility which will be their most advanced facility outside of Taiwan. The new foundry will likely be popular with US customers and military applications requiring more secure facilities.

Intel has finally sounded the "full steam ahead" whistle for its Fab 42, set in Arizona. Fab 42 has a storied past to it, as Intel started its construction back in 2011. It was actually finished by 2013, and by 2014 all essential infrastructure for semiconductor fabrication was there - except for the fabrication equipment itself. You see, Intel aimed for this factory to produce 450 mm wafers (instead of the industry standard 300 mm) in the 14 nm process. However, back in 2014, Intel wasn't sure about demand for its 14 nm products - and the company was actually planning to debut 10 nm back in 2016, so it sort of made sense. Of course, then came the 10 nm delays, the 14 nm supply issues, and backporting of certain products to other less cutting-edge processes. If only Intel had had a crystal ball.

TSMC has just recently announced that they will be building a semiconductor factory in the US, thanks to the pressure from Trump administration. The 5 nm Fab will be built in Arizona, with construction starting in 2021. It will be finished in the year 2024 when the plant will operate at a capacity of 20,000 wafers per month. This is not a high number as TSMC Fabs usually operate at a rate of 100-150K wafers per month, however, the amazing thing is the location of the Fab. The US Fab in Arizona is set to change the global landscape of the semiconductor supply chain, as per the latest report from DigiTimes Research.

Arizona is a place in the US where lots of companies are building semiconductors. Intel, Raytheon, Microchip, ON Semiconductor, VLSI, Freescale, NXP, STMicroelectronics, Honeywell, Marvel, Amkor, Philips, and Western Digital have their facilities there and Arizona can be considered one of the key places for semiconductor manufacturing in the US. With TSMC adding their manufacturing facilities to that list as well, there could be a change in the supplier ecosystem. In light of the need for TSMC 5 nm Fab, the world's leading OSAT (Outsourced Semiconductor Assembly and Test) suppliers may be encouraged to set up local production in Arizona to help TSMC with its plans. A lot of OSAT providers are headquartered in Taiwan, however, if there is a need, they are possibly going to build their manufacturing facilities in Arizona. This alone could change the way semiconductor manufacturing facilities are supplied, and the US could become a major center of OSAT providers.
