Running Bull, the WSJ story refers to some kind of patented barrier between the U and the Si. I wonder about this barrier. It says it is patented, which presumably means that it was invented several years ago. I wonder who invented it, and who will be able to get rights to it? If it is IBM, I understand that IBM has patent cross-licensing agreements with lots of companies.

Here is the excerpt from the story ...
