Future of Nano-CMOS Technology
[attachment=17842]
Reduce Capacitance
Reduce switching time of MOSFETs
Reduce power consumption
2. Increase number of Transistors
Increase functionality
Parallel processing
Increase circuit operation speed
Thus, downsizing of Si devices is
the most important and critical issue.
Already 32 Gbit:
larger than that of world population
comparable for the numbers of neurons
in human brain
Samsung announced 256 Gbit will be produced in 2010.
Only 4 years from now.
256Gbit: larger than those of # of stars in galaxies
After 2020
There is no decrease in gate length around at 5 nm due to
subthreshold leakage.
It is not useful to reduce the gate length any more for
increasing the drain current, because the conduction is
already semi-ballistic.
What is important for keeping Moore Law, then?
Increase drain current drive under low drain voltage
in order to reduce the power consumption.
