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]

Design

"28nm" requires twice the number of design rules for ensuring reliability in manufacturing as "80nm".^[10]

Shipped devices

AMD's Radeon HD 7970 uses a graphics processing unit manufactured using a "28nm" process.^[11]

Some models of the PS3 use a RSX 'Reality Synthesizer' chip manufactured using a "28nm" process.^[12]

FPGAs produced with "28 nm" process technology include models of the Xilinx Artix 7 FPGAs and Altera Cyclone V FPGAs.^[13]
