A process can include forming a doped semiconductor layer over a substrate. The process can also include performing an action that reduces a dopant content along an exposed surface of a workpiece that includes the substrate and the doped semiconductor layer. The action is performed after forming the doped semiconductor layer and before the doped semiconductor layer is exposed to a room ambient. In particular embodiments, the doped semiconductor layer includes a semiconductor material that includes a combination of at least two elements selected from the group consisting of C, Si, and Ge, and the doped semiconductor layer also includes a dopant, such as phosphorus, arsenic, boron, or the like. The action can include forming an encapsulating layer, exposing the doped semiconductor layer to radiation, annealing the doped semiconductor layer, or any combination thereof.
