Abstract
Semiconductor devices and methods of manufacturing semiconductor devices are described herein. A method includes implanting neutral elements into a dielectric layer, an etch stop layer, and a metal feature, the dielectric layer being disposed over the etch stop layer and the metal feature being disposed through the dielectric layer and the etch stop layer. The method further includes using a germanium gas as a source for the neutral elements and using a beam current above 6.75 mA to implant the neutral elements.
