摘要： A method for depositing silicon oxide layers having a low dielectric constant by reaction of an organosilicon compound and a hydroxyl forming compound at a substrate temperature less than about 400° C. The low dielectric constant films contain residual carbon and are useful for gap fill layers, pre-metal dielectric layers, inter-metal dielectric layers, and shallow trench isolation dielectric layers in sub-micron devices. The hydroxyl compound can be prepared prior to deposition from water or an organic compound. The silicon oxide layers are preferably deposited at a substrate temperature less than about 40° C. onto a liner layer produced from the organosilicon compound to provide gap fill layers having a dielectric constant less than about 3.0.

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.
