Semiconductor lithography method
The "28 nm" lithography process is a half-node semiconductor manufacturing process based on a die shrink of the "32 nm" lithography process .[ 1] It appeared in production in 2010.[ 2]
Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no direct relation to the dimensions on the integrated circuit;[ 3] neither gate length, metal pitch or gate pitch on a "28nm" device is twenty-eight nanometers.[ 4] [ 5] [ 6] [ 7]
Taiwan Semiconductor Manufacturing Company has offered "28 nm" production using high-K metal gate process technology.[ 8]
GlobalFoundries offers a "28nm" foundry process called the "28SLPe" ("28nm Super Low Power") foundry process, which uses high-K metal gate technology.[ 9]
