That was an interesting article that you posted. Paricularly intriguing is that IBM has chosen NOT to patent the barrier. A priori, this will allow anyone to rapidly figure out the composition of the layer. Since IBM presumably wants a competitive advantage from this process and that they are not brain dead, the lack of patent protection for the layer implies that IBM has developed a novel process for depositing this layer. If they had patented the layer, they would have had to divulge the manufacturing process.
