Permittivity of Oxide Layer Solution

Follow our step by step solution on how to calculate Permittivity of Oxide Layer?

FIRST Step Consider the formula

ε ox = t ox \cdot \frac{C in}{W g \cdot L g}

Next Step Substitute values of Variables

∴

ε ox = 4.98mm \cdot \frac{60.01μF}{0.285mm \cdot 7mm}

Next Step Convert Units

∴

ε ox = 0.005m \cdot \frac{6E-5F}{0.0003m \cdot 0.007m}

Next Step Prepare to Evaluate

∴

ε ox = 0.005 \cdot \frac{6E-5}{0.0003 \cdot 0.007}

Next Step Evaluate

∴

ε ox = 0.149799398496241F/m

Next Step Convert to Output's Unit

∴

ε ox = 149.799398496241μF/mm

LAST Step Rounding Answer

∴

ε ox = 149.7994μF/mm
