Abstract
A method includes etching a dielectric layer to form an opening, with an underlying region underlying the dielectric layer exposed to the opening, and performing a bombardment to bombard a surface region of the underlying region through the opening. After the bombardment, the surface region is reacted with a process gas to form a reaction layer. An anneal is then performed to remove the reaction layer.
