Oxidation resistant high conductivity copper layers for microelectronic
applications and process of making same
摘要:
A process for preparing an oxidation resistant, electrically conductive copper layer on a substrate, and copper layers so formed, are disclosed. A copper layer is deposited onto the surface of a substrate, and subsequently annealed. The copper layer includes magnesium in an amount sufficient to form an inert magnesium oxide layer at the surface of the copper layer upon annealing.
