BACKGROUND

Modern day integrated circuits (ICs) comprise millions or billions of semiconductor devices formed on a semiconductor substrate (e.g., silicon). ICs may use many different types of transistor devices, depending on application. In recent years, the increasing market for cellular and radio frequency (RF) devices has resulted in a significant increase in the demand for RF switch devices. A smartphone may, for example, incorporate 10 or more RF switch devices in its receive chain to switch a received signal to appropriate bands.
