Abstract:
Methods and devices for controlling pressures in microenvironments between a deposition apparatus and a substrate are provided. Each microenvironment is associated with an aperture of the deposition apparatus which can allow for control of the microenvironment.
Abstract:
A buffer layer is provided that can be fabricated over an OLED without the use of any oxygen-containing gas. The buffer layer reduces the possibility of damage to the underlying OLED due to use of oxygen-containing materials during deposition of subsequent barrier layers, and thereby allows for deposition of barrier layers without reducing the flexibility of the device.

Abstract:
Nozzle designs which have been found to be effective in governing overspray in OVJP are provided. Aspects of the invention have been found to be effective in reducing or avoiding sudden pressure drops at the end of the nozzle close to the substrate, and may be advantageously employed in obtaining, for example, greater consistency between the nozzle outlet diameter and the deposited pattern width.
Abstract:
Organic electronic devices comprising a covalently bonded organic/inorganic composite layer. The composite layer may be formed by the reaction of a metal alkoxide with a charge transport compound having one or more hydroxyl groups. Examples of metal alkoxides that can be used include vanadium alkoxides, molybdenum alkoxides, titanium alkoxides, or silicon alkoxides. This composite layer can be used for any of the various charge conducting layers in an organic electronic device, including the hole injection layer.
Abstract:
Embodiments of the disclosed subject matter provide a nozzle assembly and method of making the same, the nozzle assembly including a first aperture formed on a first aperture plate to eject a carrier gas flow having organic vapor onto a substrate in a deposition chamber, second apertures formed on a second aperture plate disposed adjacent to the first aperture to form a vacuum aperture, where the first aperture plate and the second aperture plate are separated by a first separator plate, third apertures formed on a third aperture plate to eject purge gas that are disposed adjacent to the second aperture plate, where the second aperture plate and the third aperture plate are separated by second separator plate, and a third separator plate is disposed adjacent to the one or more third aperture plates to form a gas channel in the one or more third aperture plates.
Abstract:
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.
Abstract:
A microfluidic device for use with a microfluidic delivery system, such as an organic vapor jet printing device, includes a glass layer that is directly bonded to a microfabricated die and a metal plate via a double anodic bond. The double anodic bond is formed by forming a first anodic bond at an interface of the microfabricated die and the glass layer, and forming a second anodic bond at an interface of the metal plate and the glass layer, where the second anodic bond is formed using a voltage that is lower than the voltage used to form the first anodic bond. The second anodic bond is formed with the polarity of the voltage reversed with respect to the glass layer and the formation of the first anodic bond. The metal plate includes attachment features that allow removal of the microfluidic device from a fixture.

Abstract:
A hybrid permeation barrier having two complementary layers is disclosed. The barrier includes a first layer with a relatively high stress-thickness in the range of −1000 MPa-μm to −200 MPa-μm and a second layer with a relatively low stress-thickness in the range −150 MPa-μm to 300 MPa-μm. The second layer compensates for the stress caused by the first, thereby allowing for a barrier that provides good permeation without causing failure of the device due to delamination.
