  • Publication number: 20240237505
    Abstract: Embodiments of the disclosed subject matter provide a laser source configured to output a laser beam, a beam transfer cavity to receive the outputted laser beam on a first side of the apparatus and output the laser beam on a second side of the apparatus, wherein the first side is opposite the second side, and a plume removal device having an exhaust aperture on the second side of the apparatus facing a heat affected zone (HAZ). A bottom surface of the plume removal device may be facing the substrate, where organic matter is disposed on the substrate, and the HAZ may be aligned with the surface of the substrate having the organic matter to be ablated by the laser beam.

  • Publication number: 20230357918
    Abstract: Methods, systems, and devices are provided for organic vapor jet deposition (OVJP), which require significantly fewer print heads than conventional OVJP deposition systems. The disclosed OVJP systems include half the number of OVJP print heads than a conventional system, or less, and provide for relative movement of the substrate and print heads to allow for rapid and comprehensive material deposition over the full surface of the substrate.

  • Publication number: 20230255098
    Abstract: A chuck for holding a workpiece in a deposition system is provided, which includes a base having a base surface with a flatness tolerance of not greater than 30 µm and a clamp having a surface configured to be attached to a substrate, which has a flatness tolerance of not greater than 30 µm. The clamp also includes a substrate holder configured to hold a substrate above the second clamp surface.
