    Abstract: Embodiments of the disclosed subject matter provide a depositor device having a first exhaust aperture and a second exhaust aperture, and a plurality of delivery apertures disposed between the first exhaust aperture and the second exhaust aperture. A first aperture of the plurality of delivery apertures may have a first length, and a second aperture of the plurality of delivery apertures may have a second length. The first length may be longer than the second length. The device may include a third aperture of the plurality of delivery apertures which may have a third length, where the second length may be longer that the third length. The plurality of delivery apertures of the device may include three or more delivery apertures having different lengths.

    Abstract: 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.

    Abstract: Embodiments of the disclosed subject matter provide a micronozzle array formed from monolithic silicon. The micronozzle array may have a plurality of nozzles, where each nozzle of the plurality of nozzles including an integrated plug valve that allows flow from the nozzle to be attenuated separately from each other nozzle of the plurality of nozzles. Each of the plurality of nozzles may include a microchannel, formed from the monolithic silicon, having a first channel portion and a second channel portion, where the first channel portion is narrower than the second channel portion, and where the first channel portion forms an aperture of the nozzle that is configured to eject vapor from the microchannel. Each of the plurality of nozzles may include a stem, formed from the monolithic silicon that includes the integrated plug valve is suspended in the microchannel to attenuate the flow from the nozzle.

    Abstract: Embodiments of the disclosed subject matter provide a device having a print head that includes a micronozzle array of depositors to deposit a material on a substrate. A reflective optical device may reflect a signal output by at least one optical sensor, and to reflect the signal from a surface of the substrate to the optical sensor. A processor may determine a distance between the optical sensor and the target surface of the substrate. The device may include one or more actuators coupled to the at least one print head to move the print head relative to an internal reference frame and adjust a position of the print head to the substrate. The sensor may be fixedly coupled with a mount to the internal reference frame. The print head may be configured to move independently of the optical sensor in at least one axis of linear or rotational motion.
