| 20080305629 | TUNGSTEN NITRIDE ATOMIC LAYER DEPOSITION PROCESSES - In one embodiment, a method for forming a tungsten barrier material on a substrate is provided which includes depositing a tungsten layer on a substrate during a vapor deposition process and exposing the substrate sequentially to a tungsten precursor and a nitrogen precursor to form a tungsten nitride layer on the tungsten layer. Some examples provide that the tungsten layer may be deposited by sequentially exposing the substrate to the tungsten precursor and a reducing gas (e.g., diborane or silane) during an atomic layer deposition process. The tungsten layer may have a thickness of about 50 Å or less and tungsten nitride layer may have an electrical resistivity of about 380 μΩ-cm or less. Other examples provide that a tungsten bulk layer may be deposited on the tungsten nitride layer by a chemical vapor deposition process. | 12-11-2008 |
| 20100029094 | Method and Apparatus for Forming a High Quality Low Temperature Silicon Nitride Layer - A method of forming a silicon nitride layer is described. According to the present invention, a silicon nitride layer is deposited by thermally decomposing a silicon/nitrogen containing source gas or a silicon containing source gas and a nitrogen containing source gas at low deposition temperatures to form a silicon nitride layer. The thermally deposited silicon nitride layer is then treated with hydrogen radicals to form a treated silicon nitride layer. | 02-04-2010 |
