Abstract:
A method of plasma processing, comprising the steps of:(a) positioning a substrate in a chamber; (b) flowing one or more process gases into the chamber; (c) igniting a plasma from the one or more process gases by applying a plasma source power at a first power level; (d) depositing a material layer on the substrate; (e) ramping down the plasma source power below the first power level; (f) terminating at least one gas flow from the one or more process gases prior to terminating the plasma, wherein the at least one gas flow comprises a precursor gas for the deposited material, wherein the precursor gas is selected from the group of tetraethoxy-silane and tetramethyl cyclotetra-siloxane, wherein the deposited material is oxide, and wherein the ramping down of the plasma source power is performed concurrently with the terminating at least one gas flow from the one or more process gases; and (g) terminating the plasma.
