Abstract
The present invention relates to a chemical mechanical polishing (CMP) machine and method in which at least one polishing device is provided with a vertically-oriented polishing surface and a slurry delivery mechanism. As a result, the footprint of the machine is greatly reduced and the prevention of contaminants embedding in the polishing device can be promoted.
