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: 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.
