Size Adjustable and Changeable Capacity Diode

This invention is about size adjustable and changeable capacity diode which gives more flexibility designing Epi layer and which has electric capacity and can be designed with other active chips. According to the invention, size adjustable and changeable capacity diode, which is processed with the combination of active layer etching, selective Epi layer growth, ion insertion, is provide. Such size adjustable and changeable capacity diode changes electricity capacity as pattern of mask so that it is more compatible with other chips and has bigger electric capacity.
