发明名称 PECVD MULTI-STEP PROCESSING WITH CONTINUOUS PLASMA
摘要 Embodiments of the present invention provide methods for reducing defects during multi-layer deposition. In one embodiment, the method includes exposing the substrate to a first gas mixture and an inert gas in the presence of a plasma to deposit a first material layer on the substrate, terminating the first gas mixture when a desired thickness of the first material is achieved while still maintaining the plasma and flowing the inert gas, and exposing the substrate to the inert gas and a second gas mixture that are compatible with the first gas mixture in the presence of the plasma to deposit a second material layer over the first material layer in the same processing chamber, wherein the first material layer and the second material layer are different from each other.
