| 20100243440 | Mechanism for continuously varying radial position of a magnetron - A continuously variable multi-position magnetron that is rotated about a central axis in back of a sputtering target at a freely selected radius. The position is dynamically controlled from the outside, for example, through a hydraulic actuator connected between a pivoting arm supporting the magnetron and an arm fixed to the shaft, by two coaxial shafts independent controllable from the outside and supporting the magnetron through a frog-leg mechanism, or a cable connected between the pivoting arms and moved by an external slider. The magnetron can be rotated at two, three, or more discrete radii or be moved in a continuous spiral pattern. | 09-30-2010 |
| 20090280640 | DEPOSITION AND DENSIFICATION PROCESS FOR TITANIUM NITRIDE BARRIER LAYERS - In one embodiment, a method for forming a titanium nitride barrier material on a substrate is provided which includes depositing a titanium nitride layer on the substrate by a metal-organic chemical vapor deposition (MOCVD) process, and thereafter, densifying the titanium nitride layer by exposing the substrate to a plasma process. In one example, the MOCVD process and the densifying plasma process is repeated to form a barrier stack by depositing a second titanium nitride layer on the first titanium nitride layer. In another example, a third titanium nitride layer is deposited on the second titanium nitride layer. Subsequently, the method provides depositing a conductive material on the substrate and exposing the substrate to a annealing process. In one example, each titanium nitride layer may have a thickness of about 15 Å and the titanium nitride barrier stack may have a copper diffusion potential of less than about 5×10 | 11-12-2009 |
