hafnium? How much of that is there on earth/how easy is it to mine? I hope the mining of it isn't a major environmental nightmare like so many metals. I wonder if this will change the market for hafnium seriously.
other than that, yay 45 nm!
Considering that the Hafnium is supposed to replace the gate dielectric with a thickness of 1.2 nm (that is nanometer, that is 1 billionth of a meter), I don't think we have to worry.
Assuming a 200 square millimeter chip, one cubic centimetre of Hafnium would be enough for four million chips. It's density is quite high at 13.3 gram per cubic centimeter, even so, one gram will be enough for about 300,000 chips.
