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]
Taiwan Semiconductor Manufacturing Company has offered 28 nm production using high-K metal gate process technology.[3]
GlobalFoundries offers a 28nm foundry process called the 28SLPe (28nm Super Low Power) foundry process, which uses high-K metal gate technology.[4]
Design
28nm requires twice the number of design rules for ensuring reliability in manufacturing as 80nm.[5]
Shipped devices
AMD's Radeon HD 7970 uses a graphics processing unit manufactured using a 28nm process.[6]
Some models of the PS3 use a RSX 'Reality Synthesizer' chip manufactured using a 28nm process.[7]
FPGAs produced with 28 nm process technology include models of the Xilinx Artix 7 FPGAs and Altera Cyclone V FPGAs.[8]
