In semiconductor fabrication, the International Technology Roadmap for Semiconductors (ITRS) defines the "10 nanometer process" as the MOSFET technology node following the "14 nm" node.
Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no relation to the dimensions on the integrated circuit;[1] neither gate length, metal pitch or gate pitch on a "10nm" device is ten nanometers.[2][3][4] For example, GlobalFoundries' "7 nm" processes are dimensionally similar to Intel's "10 nm" process.[5] TSMC and Samsung's "10 nm" processes are somewhere between Intel's "14 nm" and "10 nm" processes in transistor density. The transistor density (number of transistors per square millimetre) is more important than transistor size, since smaller transistors no longer necessarily mean improved performance, or an increase in the number of transistors.[citation needed]
All production "10 nm" processes are based on FinFET (fin field-effect transistor) technology, a type of multi-gate MOSFET technology that is a non-planar evolution of planar silicon CMOS technology. Samsung first started their production of "10 nm-class" chips in 2013 for their multi-level cell (MLC) flash memory chips, followed by their SoCs using their 10 nm process in 2016. TSMC began commercial production of "10 nm" chips in 2016, and Intel later began production of "10 nm" chips in 2018.[needs update]
