Claim Text:
1. A method of forming a buffer layer on a surface of a substrate, comprising: providing a substrate having a planarization material disposed on an OLED device formed on the substrate in a processing chamber, wherein the planarization material is a polymer material substantially encapsulating entire structures of the OLED device; supplying a buffer layer gas mixture including a silicon containing gas into the processing chamber; controlling a substrate temperature less than about 100 degrees Celsius; forming a buffer layer on the planarization material to encapsulate the OLED device, wherein the buffer layer is an inorganic material; supplying an encapsulating barrier layer deposition gas mixture including a silicon containing gas and a nitrogen containing gas into the processing chamber; and forming an encapsulating barrier layer on the buffer layer encapsulating the OLED device.
