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: Methods of fabricating a device having laterally patterned first and second sub-devices, such as subpixels of an OLED, are provided. Exemplary methods may include depositing via organic vapor jet printing (OVJP) a first organic layer of the first sub-device and a first organic layer of the second sub-device. The first organic layer of the first sub-device and the first organic layer of the second sub-device are both the same type of layer, but have different thicknesses. The type of layer is selected from an ETL, an HTL, an HIL, a spacer and a capping layer.

Abstract: Sources, devices, and techniques for deposition of organic layers, such as for use in an OLED, are provided. A vaporizer may vaporize a material between cooled side walls and toward a mask having an adjustable mask opening. The mask opening may be adjusted to control the pattern of deposition of the material on a substrate, such as to correct for material buildup that occurs during deposition. Material may be collected from the cooled side walls for reuse.

Abstract: A novel thin film encapsulated OLED panel architecture and a method for making the panels with improved shelf life is disclosed. The OLED panel consists of a plurality of OLED pixels; each OLED pixel is individually hermetically sealed and isolated from its neighboring pixels. The organic stack of the OLED pixel is contained within its own hermetically sealed structure, achieved by making the structure on a barrier coated substrate and using a first barrier material as the grid and a second barrier for encapsulating the entire OLED pixel. The first barrier material provides the edge seal while the second barrier disposed over the pixel provides protection from top down moisture diffusion. By isolating and hermetically sealing individual pixels; any damage such as moisture and oxygen ingress due to defects or particles, delamination, cracking etc. can be effectively contained within the pixel thereby protecting other pixels in the panel.

Abstract: Methods of modulating flow during vapor jet deposition of organic materials are provided. A method may include ejecting a vapor entrained in a delivery gas from a nozzle onto a substrate upon which the vapor condenses. A confinement gas may be provided that has a flow direction opposing a flow direction of the delivery gas ejected from the nozzle. A vacuum source may be provided that is adjacent to a delivery gas aperture of the nozzle. The method may include adjusting, by an actuator, a fly height separation between a deposition nozzle aperture of the nozzle and a deposition target.

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.
