Abstract

This study focused on the development of in-situ passivation system and characterization of OLED display. The thin film passivation process with thin film layers was investigated using in-situ passivation technique in the cluster system. Thin films of $SiO_2$, SiNx passivation were manufactured using PECVD, which enables the deposition process at room temperature. The cluster system was created to develop in-situ passivation process, which OLED and thin film were fabricated in the cluster system without exposing to the atmospheric environment. It is expected that the in-situ passivation system of OLED with organic and inorganic layer provides the leading technique to develop flexible OLED.
