Enter the material resistivity and thickness into the calculator to determine the sheet resistance.
Sheet Resistance Calculation Formula
The following formula is used to calculate the sheet resistance from material resistivity and thickness.
Sheet Resistance = Material Resistivity / Thickness
Variables:
- Sheet Resistance is the resistance of the material per square (Ω/□)
- Material Resistivity is the resistivity of the material (Ω·cm)
- Thickness is the thickness of the material (cm)
To calculate the sheet resistance, divide the material resistivity by the thickness of the material.
What is Sheet Resistance Calculation?
Sheet resistance calculation refers to the process of determining the resistance of a thin film of material when the current flows laterally through the film. This is an important parameter in the design and analysis of electronic materials and devices, particularly in semiconductor manufacturing and thin film technologies.
How to Calculate Sheet Resistance?
The following steps outline how to calculate the sheet resistance using the given formula.
- First, determine the material resistivity and thickness.
- Next, use the formula: Sheet Resistance = Material Resistivity / Thickness.
- Finally, calculate the sheet resistance by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Material Resistivity = 1.68 Ω·cm
Thickness = 0.005 cm
FAQ
1. What is sheet resistance?
Sheet resistance is a measure of resistance of thin films that are uniform in thickness. It is commonly used to characterize materials in semiconductor and thin film industries.
2. How is sheet resistance different from bulk resistance?
Bulk resistance refers to the resistance of a three-dimensional material, whereas sheet resistance is specific to thin films and is measured per square unit.
