>>11628692"the transistor gate length has been reduced to <5µm (1975 tech. level) "
http://sam.zeloof.xyz/first-ic/11 components (6 TR, 2 D, 2 R, 1 C) in ~3 x 1.5mm (excluding pads)
avg ~0.75mm^2 / transitor
avg ~0.4 mm^2 / component
Intel 4004: 2250 transistors (10µm), 144 mm^2
-> 1690 mm^2
10 times worse... but it is analog.
For digital components it can surely be made more compact.
