ENHANCING ELECTRICAL PROPERTY AND UV COMPATIBILITY OF ULTRATHIN BLOK BARRIER FILM

摘要

Embodiments described herein generally relate to the formation of a UV compatible barrier stack. Methods described herein can include delivering a process gas to a substrate positioned in a process chamber. The process gas can be activated to form an activated process gas, the activated process gas forming a barrier layer on a surface of the substrate, the barrier layer comprising silicon, carbon and nitrogen. The activated process gas can then be purged from the process chamber. An activated nitrogen-containing gas can be delivered to the barrier layer, the activated nitrogen-containing gas having a N₂:NH₃ ratio of greater than about 1:1. The activated nitrogen-containing gas can then be purged from the process chamber. The above elements can be performed one or more times to deposit the barrier stack.
