  • Patent number: 9837269
    Abstract: A method for producing a substantially planar surface for semiconductor processing to improve lithography, planarization, and other process steps that benefit from a flat substrate. The method includes depositing a first alloy to form a first layer on a substrate. The first layer has a center high deposition, meaning the height in the center of the substrate is higher than the height at the edges of the substrate. The method further includes depositing a second alloy on the first layer to form a second layer. The first alloy has a different composition than the second alloy.

    Abstract: Disclosed is an organic light emitting display device including an anode, a cathode, a plurality of organic layers and a partition member. The plurality of organic layers is disposed between the anode and the cathode, where at least one layer is separated to minimize current leakage into neighboring pixels. The partition member is disposed between the neighboring pixels and configured to separate the plurality of organic layers. The least one separated layer includes a charge generation layer. Because at least one layer is separated, current leakage into neighboring pixels can be minimized. Accordingly, defects resulting from light leakage and the mixing of colors of light from neighboring pixels may be reduced and display quality is enhanced.
