The formula to calculate Sheet Resistance (Rs) is:
\[ \text{Rs} = \frac{\text{R}}{\text{T}} \]
Where:
Sheet resistance is a measure of resistance of thin films that are uniformly thick. It is commonly used in the semiconductor industry to characterize materials such as silicon wafers or thin film coatings. It is defined as the resistivity of the material divided by its thickness, and its unit is typically expressed in ohms per square.
Let's consider an example:
Using the formula to calculate the Sheet Resistance:
\[ \text{Rs} = \frac{1.0 \times 10^{-6}}{1.0 \times 10^{-3}} = 1.0 \times 10^{-3} \, \text{ohms per square} \]
This demonstrates that with a resistivity of 1.0 × 10-6 ohm-m and a thickness of 1.0 × 10-3 meters, the sheet resistance would be 1.0 × 10-3 ohms per square.
