摘要:
A cleaning process for cleaning the surface of a substrate is disclosed, wherein the surface comprises portions of a dielectric material and portions of a conductive material. According to the method disclosed, the temperature at the surface of the substrate is kept below a predefined value during the actual cleaning step in a reactive and/or inert plasma ambient, such as an argon gas ambient, wherein the predefined value corresponds to the surface temperature at which agglomeration of the conductive material occurs.
