摘要： A silicon oxide layer is produced by plasma enhanced oxidation of an organosilicon compound to deposit films having a carbon content of at least 1% by atomic weight. Films having low moisture content and resistance to cracking are deposited by introducing oxygen into the processing chamber at a flow rate of less than or equal to the flow rate of the organosilicon compounds, and generating a plasma at a power density ranging between 0.9 W/cm2 and about 3.2 W/cm2. An optional carrier gas may be introduced to facilitate the deposition process at a flow rate less than or equal to the flow rate of the organosilicon compounds. The organosilicon compound preferably has 2 or 3 carbon atoms bonded to each silicon atom, such as trimethylsilane, (CH3)3SiH. An oxygen rich surface may be formed adjacent the silicon oxide layer by temporarily increasing oxidation of the organosilicon compound.

摘要： An embodiment of the present invention provides methods for forming a carbon-containing layer having a low dielectric constant and good gap-fill capabilities. A method includes depositing a carbon-containing layer on a substrate and transforming the carbon-containing layer to remove at least some of the carbon. The transforming step may include annealing the carbon-containing layer in a furnace containing a hydrogen atmosphere, for example. The carbon-containing layer may be a carbon-doped silicon oxide material, where the transforming step changes the carbon-doped silicon oxide. Additionally, the method may include subjecting the annealed layer to a hydrogen and/or low oxygen plasma treatment to further remove carbon from the layer. Additionally, a step of adding a capping layer to the annealed, plasma treated material is provided. Products made by the above methods are also included, such as a product including a low k carbon-containing layer where the low k carbon-containing layer has been transformed to remove some of the carbon from the layer. An additional product includes a transformed carbon-containing layer further subjected to a hydrogen plasma treatment to remove more carbon from the layer. Further, a capping layer deposited over the transformed and hydrogen plasma treated layer is provided.
