Curing the first sublayer comprises generating water from the mixed gas plasma in a process chamber in which the curing occurs. The deposition of the first sublayer and the curing of the first sublayer is repeated one or more times to form a completed buffer layer. A second barrier layer is then deposited on the completed buffer layer.

  • Publication number: 20230172033
    Abstract: A method and apparatus for forming an encapsulation layer on an organic light emitting diode (OLED) patterned substrate are described. A sidewall planarization layer fills voids in a scalloped sidewall of a wall feature on the OLED patterned substrate. The sidewall planarization layer is cured in the same chamber as the deposition of the sidewall planarization layer. A barrier layer is formed on the sidewall planarization layer. The sidewall planarization layer provides a planarized surface for good adhesion of the barrier layer over the sidewall planarization layer which minimizes the possibility of defects to the OLED patterned substrate from moisture of oxygen penetrating the OLED patterned substrate.
