Calculate resistance of a semiconductor layer

A simple Javascript calculator for resistance of semiconductor layers.

The resistance of a resistive layer on an ASIC/IC is usually given (for hand calculations ) by taking the ratio of the length of the layer and its width and multiplying by its sheet resistance, (L/W)RS. Where L is the length, W is the width and RS is the sheet resistance. (Not every resistor can be calculated this way. Odd shapes are not amenable to this formula.) A simple javascript was generated at SPG that can be modified as needed to do this. Please visit the Signal Processing Group website to download the calculator free of cost. The calculator may be found under the “calculators” menu item.
