摘要： Embodiments of the disclosed subject matter provide a device including a micronozzle array having separate redundant groups of depositors that each include a delivery aperture disposed between two exhaust apertures. The device may include a first row of depositors of a first redundant group, each of which may be connected in parallel to first common delivery lines and first common exhaust lines. The device may include a second row of depositors of a second redundant group, each of which is connected in parallel to second common delivery and second common exhaust lines. The first row of depositors and the second row of depositors may operate independently from one another. The device may be disposed within a deposition chamber and in proximity of a substrate.

摘要： Systems and techniques for depositing organic material on a substrate are provided, in which one or more shield gas flows prevents contamination of the substrate by the chamber ambient. Thus, multiple layers of the same or different materials may be deposited in a single deposition chamber, without the need for movement between different deposition chambers, and with reduced chance of cross-contamination between layers.

摘要： Embodiments of the disclosed subject matter provide a vapor distribution manifold that ejects organic vapor laden gas into a chamber and withdraws chamber gas, where vapor ejected from the manifold is incident on, and condenses onto, a deposition surface within the chamber that moves relative to one or more print heads in a direction orthogonal to a platen normal and a linear extent of the manifold. The volumetric flow of gas withdrawn by the manifold from the chamber may be greater than the volumetric flow of gas injected into the chamber by the manifold. The net outflow of gas from the chamber through the manifold may prevent organic vapor from diffusing beyond the extent of the gap between the manifold and deposition surface. The manifold may be configured so that long axes of delivery and exhaust apertures are perpendicular to a print direction.

摘要： Systems and arrangements of OVJP deposition devices are provided, in which one or more organic material crucibles are directly attached to an injection block and a print head without the need for external delivery components such as feedtubes. Each crucible may be hermetically sealed until it is attached to the injection block, allowing for a single device to provide for storage, transport, and deposition of the organic material.
