  • Patent number: 9023683
    Abstract: A method is provided for forming an epoxy-based planarization layer overlying an organic semiconductor (OSC) film. Generally, the method forms a fluoropolymer passivation layer overlying the OSC layer. A photopatternable adhesion layer is formed overlying the fluoropolymer passivation layer, and patterned. A photopatternable planarization layer, comprising an epoxy-based organic resin, is formed overlying the photopatternable adhesion layer and patterned to expose the fluoropolymer passivation layer. Then, the fluoropolymer passivation layer is plasma etched to expose the OSC layer. More explicitly, the method can be used to fabricate a bottom gate or top gate organic thin-film transistor (OTFT). Top gate and bottom gate OTFT devices are also provided.

  • Patent number: 8995022
    Abstract: An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.
