{{Semiconductor manufacturing processes}}
The 180 nm process is a MOSFET (CMOS) semiconductor process technology that was commercialized around the 1998–2000 timeframe by leading semiconductor companies, starting with TSMC and Fujitsu, then followed by Sony, Toshiba,{{cite news |title=EMOTION ENGINE AND GRAPHICS SYNTHESIZER USED IN THE CORE OF PLAYSTATION BECOME ONE CHIP |url=https://www.sie.com/content/dam/corporate/en/corporate/release/pdf/030421be.pdf |access-date=26 June 2019 |publisher=Sony | date=April 21, 2003}} Intel, AMD, Texas Instruments and IBM.
History
The origin of the 180 nm value is historical, as it reflects a trend of 70% scaling every 2–3 years.{{Citation needed|date=February 2021}} The naming is formally determined by the International Technology Roadmap for Semiconductors (ITRS).
Some of the first CPUs manufactured with this process include Intel Coppermine family of Pentium III processors. This was the first technology using a gate length shorter than that of light used for contemporary lithography, which had a wavelength of 193 nm.{{Citation needed|date=February 2021}}
Some more recent{{When|date=February 2021}} microprocessors and microcontrollers (e.g. PIC) are using this technology because it is typically low cost and does not require upgrading of existing equipment.{{Citation needed|date=February 2021}} In 2022, Google sponsored open-source hardware projects using GlobalFoundries 180nm MCU (microcontroller) process on multi-project wafers.{{Cite web |title=Google funds open source silicon manufacturing shuttles for GlobalFoundries PDK |url=https://opensource.googleblog.com/2022/10/announcing-globalfoundries-open-mpw-shuttle-program.html |access-date=2022-11-16 |website=Google Open Source Blog}}
