Abstract:
1. A method for manufacturing an inorganic thin film electroluminescent device, comprising the steps of: forming a lower electrode; forming a lower insulating layer on the lower electrode; forming a phosphor on the lower insulating layer; forming an upper insulating layer on the phosphor; and forming an upper electrode on the upper insulating layer, wherein at least one of the steps of forming the lower insulating layer and the upper insulating layer is a step of forming a multi-layered insulating layer having a low-k film and a high-k film, which is contacted with the phosphor; and wherein the step of forming the insulating layer or the dielectric film (the high-k film or the low-k film) comprises one or more than two PEALD cycles, each PEALD cycle comprising the steps of: injecting a precursor; performing a first purge; applying direct plasma while injecting a reaction gas; and performing a second purge.
