  • Publication number: 20260124339
    Abstract: Embodiments of the disclosed subject matter provide a method of coating a surface with an active pharmaceutical ingredient, where an organic source having a first organic material may be heated to create an organic vapor, the first organic material having an active pharmaceutical ingredient. The source vapor may be transported via an inert carrier gas to a confined organic printing COP depositor in a deposition chamber. The organic vapor entrained in the inert carrier gas may be ejected from the COP depositor toward a surface to cause the first organic material to condense on the surface.

  • Patent number: 12618136
    Abstract: Devices and techniques that include use of a capacitive sensor to permit an OVJP print head to orient itself relative to conductive or dielectric traces on a printing substrate are disclosed. Such a sensor enables real-time measurement and closed-loop control of print head position with respect to substrate traces. This enables, for example, micron scale resolution in a dimension transverse to printing while permitting both the substrate and movement of the OVJP tool to scale to larger sizes than are achievable using conventional techniques and systems.

  • Publication number: 20250179628
    Abstract: A vapor deposition system comprising an array of depositors in fluid communication with an ambient inert gas that are held in proximity to substrate carried on a heated conveyance such that the substrate and depositors move relative to each other during deposition. Here, each depositor has one or more delivery apertures that ejects a gas jet including a vapor precursor that chemically reacts with the substrate surface to form a single-molecule thick layer of electroluminescent compound on the substrate. Further, each depositor has one or more exhaust apertures that cumulatively withdraw a greater molar flow of gas than is cumulatively ejected by the delivery apertures in the same depositor.

  • Patent number: 12318805
    Abstract: Embodiments of the disclosed subject matter provide a device that may have a first depositor that includes one or more delivery apertures surrounded by one or more exhaust apertures, where the one or more delivery apertures and the one or more exhaust apertures are enclosed within a perimeter of a boss that protrudes from a substrate-facing side of the one or more delivery apertures. The delivery channels for the one or more delivery apertures and exhaust channels for the one or more exhaust apertures may be routed orthogonally to each other. The one or more delivery apertures may be configured to permit jets of delivery gas pass through a lower surface of the first depositor. The lower surface of the first depositor may include the one or more exhaust apertures to remove surplus vapor from a delivery zone. Embodiments may also provide a method of forming a print head.
