A method for forming integrated dielectric layers using plasma energy includes (i) depositing a first dielectric layer on a substrate using a first reaction gas comprised of a source gas at a first source gas flow rate and an inert gas at a first inert gas flow rate, wherein the first inert gas flow rate is no more than 40% of the first source gas flow rate, and (ii) continuously depositing a second dielectric layer on top of the first dielectric layer using a second reaction gas comprised of a source gas at a second source gas flow rate and an inert gas at a second inert gas flow rate, wherein the second inert gas flow rate is 40% or higher of the second source gas flow rate.

Method for forming integrated dielectric layers

Provided herein is a method for cleaning CVD reaction chambers with active oxygen species. The active oxygen species may also be mixed with active fluorine species. The active oxygen species are products of a plasma, which may be either generated within the CVD reaction chamber or generated remotely and introduced into the CVD reaction chamber.
