Sheet resistance

Electrical resistance of a thin film

Sheet resistance is the resistance of a square piece of a thin material with contacts made to two opposite sides of the square. It is usually a measurement of electrical resistance of thin films that are uniform in thickness. It is commonly used to characterize materials made by semiconductor doping, metal deposition, resistive paste printing, and glass coating. Examples of these processes are: doped semiconductor regions, and the resistors that are screen printed onto the substrates of thick-film hybrid microcircuits.
