Abstract: A method of forming a semiconductor material incorporating an electrical dopant is disclosed. In one aspect, a method of incorporating dopant in a semiconductor film comprises forming a first semiconductor material incorporating the dopant at a first dopant concentration and preferentially etching a portion of the first semiconductor material, wherein etching leaves a first etched semiconductor material incorporating the dopant at a second dopant concentration higher than the first dopant concentration.
