industrial atomic scale 3d printing

how to build a computer chip atom by atom at an industrial scale 

to 3d print a computer chip one atom at a time takes too long time 

if the computer chip is made of silicon 

what's needed is a fluid or powder 

with each molecule containing one or multiple silicon atoms 

then a laser or electricity or other type of energy 

energizes spot where silicon atom is supposed to connect to surface of computer chip 

the molecule containing silicon atom needs to have a bond with silicon atom that disconnects with it's silicon atom 

when silicon atom connects to surface of computer chip 

if laser is used 

then there would be multiple lasers that would quickly energize different parts of the surface of the computer chip 

to make the computer chip grow one atom at a time at multiple places at the same time 

my guess is that it would be polymer molecules with one or multiple silicon atoms 

if it's a fluid of polymer moldcules containing silicon atoms 

then that fluid would probably have to be very thin to enable lasers to penetrate easily and quickly without heating fluid 

if computer chip is not built by silicon atoms, 

then maybe some metal atoms or carbon atoms could be used 

instead of a 3d printer needle putting atom by atom on a surface 

it's a thin fluid covering a surface with many lasers energizing multiple points of the surface 

to make a structure grow on the surface 

which is extremely faster and likely cheaper 

difficult part is describing with words what mind sometimes sees visually
