Improved step coverage for pulsed plasma deposition etch |
| abstract |
Embodiments of the present disclosure relate to methods of in-situ deposition and treatment of thin films to improve step coverage. In one embodiment, a method for processing a substrate is provided. The method comprises the following steps: forming a dielectric layer on a plurality of patterned features of a substrate by exposing the substrate to a gas mixture of a first precursor and a second precursor while a plasma is present in a process chamber, wherein the plasma is formed by a first pulsed RF power; exposing the dielectric layer to a first plasma treatment using a gas mixture of nitrogen and helium in a process chamber; and performing a plasma etch process by exposing the dielectric layer to a plasma formed from a gas mixture of a fluorine-containing precursor and a carrier gas, wherein the plasma is formed in the process chamber by a second pulsed RF power. |
