    摘要： Methods for forming a coating over a surface are disclosed. A method includes directing a first source of barrier film material toward a substrate in a first direction at an angle θ relative to the substrate, wherein θ is greater than about 0° and less than about 85°. Additionally, a method of depositing a barrier film over a substrate includes directing a plurality of N sources of barrier film material toward a substrate, each source being directed at an angle θN relative to the substrate, wherein for each θN, θ is greater than about 0° and less than about 180°. For at least a first of the θN, θN is greater than about 0° and less than about 85°, and for at least a second of the θN, θN is greater than about 95° and less than about 180°.

    摘要： Embodiments of the present invention provide electronic devices such as OLEDs that have enhanced mechanical integrity and prolonged shelf, by minimizing the spread of a delamination region using topographical non-uniformities introduced in the device structure. For example, a device may be made deliberately non-planar by introducing multiple energy barriers which can prevent or minimize the propagation of a delamination, because the delamination will have to cross the energy barriers in order to spread to a larger area.
