Capacitor

This model applies well to many practical capacitors which are constructed of metal sheets separated by a thin layer of insulating dielectric, since manufacturers try to keep the dielectric very uniform in thickness to avoid thin spots which can cause failure of the capacitor. Since the separation between the plates is uniform over the plate area, the electric field between the

An MOS capacitor (Fig. 5–1) is made of a semiconductor body or substrate, an insulator film, such as SiO2, and a metal electrode called a gate. The oxide film can be as thin as 1.5 nm. One nanometer is equal to 10 Å, or the size of a few oxide molecules. Before 1970, the gate was typically made of metals such as Al (hence the M in MOS).
