Abstract
A capacitor may be formed by implanting after forming a dielectric and a conductive layer over a semiconductor structure. This diminishes the implant damage to the region underneath the conductive layer. Implanted impurities may be driven under the conductive layer such that two opposed impurity profiles overlap. This forms a junction under the conductive layer.
