The 32 nanometer (32 nm) node is the step following the 45 nanometer process in CMOSsemiconductor device fabrication. "32 nanometer" refers to the average half-pitch (i.e., half the distance between identical features) of a memory cell at this technology level. Intel and AMD both produced commercial microchips using the 32 nanometer process in the early 2010s. IBM and the Common Platform also developed a 32 nm high-k metal gate process. Intel began selling its first 32 nm processors using the Westmere architecture on 7 January 2010. The 32 nm process was superseded by commercial 22 nm technology in 2012.
