The 130 nanometer (130 nm) process is a level of semiconductor process technology that was reached in the 2000–2001 timeframe by such leading semiconductor companies as Intel, Texas Instruments, IBM, and TSMC.

The origin of the 130 nm value is historical, as it reflects a trend of 70% scaling every 2–3 years. The naming is formally determined by the International Technology Roadmap for Semiconductors (ITRS).

Some of the first CPUs manufactured with this process include Intel Tualatin family of Pentium III processors.

In 2020, American semiconductor company SkyWater Technology, in conjunction with Google and eFabless, released their 130 nm process design kit as open-source under the Apache License.^[1] This was the first ever open-source PDK.^[2]
