BARRIER LAYER AND METHOD FOR MAKING THE SAME

摘要

The invention relates to a method for manufacturing an article comprising a barrier layer, the method comprising
- providing an metallic or metalloid layer to a surface of a substrate by electro-deposition, using a plating liquid comprising an ionic liquid and metal ions or metalloid ions, which metal ions or metalloid ions are reduced and deposited to form the metallic or metalloid layer during the electro-eleposition; and
- preferably at least partially oxidising the metallic or metalloid layer.
