The "28 nm" lithography process is a half-node
semiconductor manufacturing
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuit (IC) chips such as modern computer processors, microcontrollers, and memory chips such as NAND flash and DRAM that are ...
process based on a die shrink of the
"32 nm" lithography process. It appeared in production in 2010.
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;
neither gate length, metal pitch or gate pitch on a "28nm" device is twenty-eight nanometers.
