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.
