Abstract
An electronic device can include a semiconductor layer having a primary surface, and an isolation structure. The isolation structure can include a first well region within the semiconductor layer and having a first conductivity, a second well region within the semiconductor layer and having a second conductivity type opposite the first conductivity type, and a third well region within the semiconductor layer having the first conductivity type. The second well region can be disposed between the first and third well regions. The first, second, and third well regions can be electrically connected to one another. The electronic device can help to allow more electrons during an electrostatic discharge or similar event to flow where the electrons will be less problematic. A process of forming the electronic device may be implemented with changes to existing masks without adding any processing operations.
