Equivalent Oxide Thickness Solution

Follow our step by step solution on how to calculate Equivalent Oxide Thickness?

FIRST Step Consider the formula

EOT = t high-k \cdot (\frac{3.9}{k high-k})

Next Step Substitute values of Variables

∴

EOT = 8.5nm \cdot (\frac{3.9}{2.26})

Next Step Convert Units

∴

EOT = 8.5E-9m \cdot (\frac{3.9}{2.26})

Next Step Prepare to Evaluate

∴

EOT = 8.5E-9 \cdot (\frac{3.9}{2.26})

Next Step Evaluate

∴

EOT = 1.46681415929204E-08m

Next Step Convert to Output's Unit

∴

EOT = 14.6681415929204nm

LAST Step Rounding Answer

∴

EOT = 14.6681nm
