Abstract: Integrated circuits and methods of producing such integrated circuits are provided. In an exemplary embodiment, an integrated circuit includes a deep well with a drain well overlying the deep well. A first source well also overlies the deep well, where the first source well includes a first source well concentration of conductivity determining impurities. A second source well overlies the first source well, where the second source well includes a second concentration of conductivity determining impurities that is higher than the first source well concentration. A drain overlies the drain well and a source overlies the second source well. A channel is defined between the source and the drain and a gate overlies the channel.
