  • Patent number: 7148624
    Abstract: A method to ensure uniform deposition of organic layer is disclosed. Since the organic layer is very thin, any deviation from the target thickness will result in visible optical defects. A homogenous layer which exhibits good coating behaviour with organic materials is provided beneath the organic layer. By covering the metal interconnects, the adverse effect on the uniformity of the polymer layer is reduced or prevented.
