Sorry about the formatting as the system does this when I use my ipad or iPhone. Here's a little gem from a little known site called Wikipedia. Semiconductor manufacturing processes 10 µm – 1971 3 µm – 1975 1.5 µm – 1982 1 µm – 1985 800 nm – 1989 600 nm – 1994 350 nm – 1995 250 nm – 1997 180 nm – 1999 130 nm – 2002 90 nm – 2004 65 nm – 2006 45 nm – 2008 32 nm – 2010 22 nm – 2012 14 nm – 2014 10 nm – 2016 7 nm – 2018 5 nm – 2020 Now reset the scale to the paradigm shift at 100nm Poet based integrated chip and onward we go Great history there by the way. The first chip looked like something out of Frankenstein. http://en.wikipedia.org/wiki/International_Technology_Roadmap_for_Semiconductors
