Semiconductor-insulator interfaces are normally occuring in every semiconductor device because they usually constitute the physical boundary of the device. The devices have a passivating coating (e.g. silicon dioxide for silicon devices), are encapsulated in a plastic case, or are adjacent to surrounding air. In integrated circuits they are sometimes isolated from each other by trenches filled with insulator material. From this it is evident that boundary conditions for semiconductor-insulator interfaces are an indispensable component of any device simulator.
