  • Publication number: 20130087779
    Abstract: There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer having a first surface energy; treating the first layer with a priming material to form a priming layer; exposing the priming layer patternwise with radiation resulting in exposed areas and unexposed areas; developing the priming layer to effectively remove the priming layer from the unexposed areas resulting in a first layer having a pattern of priming layer, wherein the pattern of priming layer has a second surface energy that is higher than the first surface energy; and forming the second layer by liquid depositions on the pattern of priming layer on the first layer.
