The 14 nanometer (14nm) process is a chip manufacturing process introduced by Intel Corporation in 2014 for the production of computer processors and other integrated circuits. This process uses advanced three-dimensional transistor technology, which improves chip performance and power consumption efficiency compared to previous processes. The 14nm process also enables the production of smaller chips, making computer devices more compact and efficient. At present, the 14nm process has been widely used in many brands of computer processors, and has become one of the current mainstream chip manufacturing processes.
