Fluorine-containing polymerized HMDSO applications for OLED thin film encapsulation

摘要

Methods for forming an OLED device are described. An encapsulation structure having organic buffer layer and an interface layer disposed on the organic buffer layer sandwiched between barrier layers is deposited over an OLED structure. In one example, the method includes depositing a first barrier layer on a region of a substrate having an OLED structure disposed thereon, depositing a buffer layer with a fluorine-containing plasma formed from a first gas mixture containing a polymer gas precursor and a fluorine containing gas on the first barrier layer, depositing an interface layer on the buffer layer with a second gas mixture containing the polymer gas precursor, and depositing a second barrier layer on the interface layer.

1. A method for forming an encapsulating structure on an organic light emitting diode (OLED) device, comprising:
depositing a first barrier layer on a region of a substrate having an OLED structure disposed thereon;depositing a buffer layer with a fluorine-containing plasma formed from a first gas mixture containing a polymer gas precursor and a fluorine containing gas on the first barrier layer;
depositing an interface layer on the buffer layer with a second gas mixture containing the polymer gas precursor, the interface layer having a gradient fluorine concentration; and depositing a second barrier layer on the interface layer.
