    • A method of depositing a silicon oxide layer over a substrate having a trench formed between adjacent raised surfaces. In one embodiment the silicon oxide layer is formed in a multistep process that includes depositing a first portion of layer over the substrate and within the trench by forming a high density plasma process that has simultaneous deposition and sputtering components from a first process gas comprising a silicon source, an oxygen source and helium and/or molecular hydrogen with highD/S ratio, for example, 10-20 and, thereafter, depositing a second portion of the silicon oxide layer over the substrate and within the trench by forming a high density plasma process that has simultaneous deposition and sputtering components from a second process gas comprising a silicon source, an oxygen source and molecular hydrogen with a lowerD/S ratio of, for example, 3-10.

    • A method and system for forming a layer on a substrate in a process chamber are provided. Deposition gases are provided to the process chamber and permitted to mix in the desired relative concentrations prior to the deposition step, resulting in improved composition uniformity of the layer. This may be accomplished by generating a heating plasma from a first gaseous mixture. The plasma is then terminated and a second gaseous mixture is provided to the process chamber such that the second gaseous mixture is substantially uniformly mixed. A second plasma is then generated from the second gaseous mixture to deposit the layer on the substrate.
    • 提供了一种用于在处理室中在基板上形成层的方法和系统。 将沉积气体提供给处理室,并允许在沉积步骤之前以期望的相对浓度混合,从而改善层的组成均匀性。 这可以通过从第一气体混合物产生加热等离子体来实现。 然后等离子体被终止,并且向处理室提供第二气体混合物,使得第二气体混合物基本均匀地混合。 然后从第二气体混合物产生第二等离子体以将该层沉积在衬底上。
