Claim Text:
1. A method for forming an encapsulating layer on an organic light emitting diode (OLED) substrate, comprising: forming a first inorganic layer on a region of a substrate and a region of a mask in a processing chamber, wherein the substrate has an OLED structure disposed thereon; forming a hybrid inorganic/organic layer on the first inorganic layer in the processing chamber; and forming a second inorganic layer on the hybrid inorganic/organic layer in the processing chamber, wherein the first inorganic layer and the second inorganic layer are formed by providing a first flow ratio of a gas comprising nitrous oxide to hexamethyldisiloxane (HMDSO) and the inorganic/organic layer is formed by providing a second flow ratio different from the first flow ratio of a gas comprising nitrous oxide to HMDSO, and wherein the mask is aligned once prior to the forming processes and is present in each of the forming processes.
