The "28 nm" lithography process is a half-node
semiconductor manufacturing 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.
