I've got this info from friends and family who work at the
local Intel fab's.....
Doesn't work that way. With a fab that runs 24x7, 350+ days a year,
every station has someone working it, the equipment is already running
as fast as possible.
More chips they make, the more profit they make. If the chip is in
demand they'll produce them as fast as possible. If the demand drops
they slow the production rate in order to keep the fab running 24x7.
If demand drops to low, they'll either move it to a smaller fab or
maybe produce the chip for only part of the year then switch to
a different chip the rest of the time.
Only way to increase production is to build/convert more fabs to making
the chip or not to shutdown on the few days a year they don't work.
(the week between Xmas and new year, maybe thanksgiving or July 4th)
It can take between 24 and 48 hours to get a fab up to 100% after a
