Abstract: A method includes forming a first dielectric layer of an interlayer dielectric (ILD) structure of a transistor device, wherein forming the first dielectric layer includes forming a first sublayer including a first dielectric material on a gate structure and forming a second sublayer including the first dielectric material on the first sublayer, wherein forming the first sublayer includes depositing the first dielectric material of the first sublayer at a first deposition rate, and wherein forming the second sublayer includes depositing the first dielectric material of the second sublayer at a second deposition rate less than the first deposition rate, and forming a second dielectric layer of the ILD structure by forming a third sublayer including a second dielectric material on the first dielectric layer using a third deposition rate, wherein the second dielectric material is different from the first dielectric material.

Abstract: Embodiments of the present disclosure generally relate to methods for forming a TFT having a metal oxide layer. The method may include forming a metal oxide layer and treating the metal oxide layer with a fluorine containing gas or plasma. The fluorine treatment of the metal oxide layer helps fill the oxygen vacancies in the metal oxide channel layer, leading to a more stable TFT and preventing a negative threshold voltage in the TFT.
