IC Gate Size Generations


  • 150-nanometer.
    This gate size was state-of-the-art in 2000. Foundries have moved beyond this size, but the military continues to use it because of the high cost of developing radiation hardened designs for smaller gates.
  • 90-nanometer.
    This gate size may be achievable for radiation-hardened ICs, but designs with smaller gates may not be able to provide radiation-hardening. Commercial applications that do not require radiation hardening have moved beyond this size.
  • 65-nanometer.
    State-of-the-art in commercial applications is moving beyond this gate size.
  • 45-nanometer.
    Current, state-of-the-art in gate size as of the time of this writing.
  • 32-nanometer.
    Gates of this size are on the drawing boards to replace 45-nanometer gates in the future.
