TL;DR: In this article, the authors developed a test rig and protocol for the characterisation of spray nozzles using a phase doppler particle analyser (PDPA), which was able to measure droplet sizes and velocities based on light-scattering principles.

12 Jul 1994TL;DR: In this paper, an RF inductively coupled plasma reactor including a vacuum chamber for processing a wafer, one or more gas sources for introducing into the chamber reactant gases, and an antenna capable of radiating RF energy into the cavity to generate a plasma therein by inductive coupling is described.
Abstract: The disclosure relates to an RF inductively coupled plasma reactor including a vacuum chamber (102) for processing a wafer (82), one or more gas sources (98, 100) for introducing into the chamber reactant gases, and an antenna (80) capable of radiating RF energy into the chamber to generate a plasma therein by inductive coupling, the antenna lying in a two-dimensionally curved surface. In another embodiment a plasma reactor includes apparatus for spaying a reactant gas at a supersonic velocity toward the portion of the chamber overlying the wafer. In a further embodiment a plasma reactor includes a planar spray showerhead for spraying a reactant gas into the portion of the chamber overlying the wafer with plural spray nozzle openings facing the wafer, and plural magnets in an interior portion of the planar spray nozzle between adjacent ones of the plural nozzle openings, the plural magnets being oriented so as to repel ions from the spray nozzle openings.

04 Sep 2002TL;DR: In this article, a non-reactive carrier gas is used to transport an organic vapor and the organic vapor is ejected through a nozzle block onto a cooled substrate, to form a patterned organic film.
Abstract: A method of fabricating an organic film is provided. A non-reactive carrier gas is used to transport an organic vapor. The organic vapor is ejected through a nozzle block onto a cooled substrate, to form a patterned organic film. A device for carrying out the method is also provided. The device includes a source of organic vapors, a source of carrier gas and a vacuum chamber. A heated nozzle block attached to the source of organic vapors and the source of carrier gas has at least one nozzle adapted to eject carrier gas and organic vapors onto a cooled substrate disposed within the vacuum chamber.

TL;DR: The transverse jet has been studied extensively because of its relevance to a wide variety of flows in technological systems, including fuel or dilution air injection in gas turbine engines, thrust vector control for high speed airbreathing and rocket vehicles, and exhaust plumes from power plants as discussed by the authors.

TL;DR: In this paper, the shape of the liquid cone and jet, the electric fields in and outside the cone, and the surface charge density at the liquid surface were calculated and compared to the droplet size scaling laws.
