Abstract
An electrical device may include a substrate; a first doped region of the substrate having a p doping type; a second doped region adjacent to the first doped region of the substrate having an n doping type, wherein an interface between the first and second doped regions forms a p-n junction; and a circuit element placed in spaced relation to the p-n junction, the circuit element configured to produce an electric field that interacts with the p-n junction to change a reverse breakdown voltage of the p-n junction. Applicants for the electrical device include ESD protection circuits.
