Abstract
A method includes implanting a first guard ring around a periphery of core circuitry. The implanting of the first guard ring includes implanting a first component a first distance from the core circuitry on a first side of the core circuitry, and implanting a second component a second distance from the core circuitry on a second side of the core circuitry, wherein the second distance is greater than the first distance. The method further includes implanting a second guard ring around the periphery of the core circuitry. The implanting of the second guard ring includes implanting a third component a third distance from the core circuitry on the first side of the core circuitry, and implanting a fourth component a fourth distance from the core circuitry on the second side of the core circuitry, wherein the third distance is greater than the fourth distance.
