Definitions

  • Fig. 2 is a schematic side view showing details of the system of Fig. 1, in accordance with an embodiment of the present invention
  • Figs. 3 - 6 are schematic, sectional views showing details of non-planar Laser-Induced Forward Transfer (LIFT) donors, in accordance with embodiments of the present invention.
  • LIFT Laser-Induced Forward Transfer
  • Apparatus 10 comprises an optical assembly 16, containing a laser and optics for Laser-Induced Forward Transfer (LIFT) .
  • Optical assembly 16 and its operations are described with reference to Fig. 2 below.
  • direct printing applications such as are performed by apparatus 10, for example as patterning or layer deposition on a PCB or FPD or any other applicable device, may comprise other diagnostics capabilities that may be in-situ (i.e., monitoring and inspecting during the printing process), integrated (i.e., monitoring and inspecting selected devices immediately after completion of the LIFT process), or offline, by a stand-alone diagnostics system.
  • laser beam 28 provides pulsed radiation on donor 22A.
  • the radiation passes through surface 23A and impinges on the donor film of a selected facet 26. Since the selected facet is not parallel to an acceptor surface 33A of substrate 24, herein assumed to be parallel to a base surface 35A of the substrate, ejection of droplets 30 of molten material from the donor film occurs at an angle 29 to acceptor surface 33A of substrate 24.
  • Acceptor surface 33A of substrate 24 is also referred to herein as top surface 33A of the substrate.
  • the ejection of droplets 30 is orthogonal to facet 26, and is indicated by an arrow 31.
  • structure 25A has surfaces, such as the sidewall, which are not parallel to acceptor surface 33A, i.e., to base surface 35A.
  • other structures 25B, 25C, 25D, 25E are mounted on substrate 24.
  • the other structures have the same property as structure 25A described here, i.e., they have surfaces which are not parallel to the base surface of substrate 24.
  • the lower surface of donor 22A comprises a periodic structure (as shown in Fig. 3) .
  • the structure of the lower surface of donor 22A may have a non-periodic structure with different slopes of facets along the lower surface of donor 22A. I.e., the structure may be different from the center of donor 22A to the edge of the donor. For example the slope angle of facets at the edge of donor 22A may be steeper than the angle of the facets at the center.

Abstract

L'invention concerne un appareil de dépôt de matériau sur une surface acceptrice comprenant un substrat donneur transparent présentant des première et seconde surfaces opposées de sorte qu'au moins une partie de la seconde surface ne soit pas parallèle à la surface acceptrice, et comprenant un film donneur sur la seconde surface. L'appareil comprend en outre un ensemble optique, qui est configuré pour diriger un faisceau de rayonnement de manière à traverser la première surface du substrat donneur et toucher le film donneur au niveau d'un emplacement sur la partie de la seconde surface qui n'est pas parallèle à la surface acceptrice, de manière à provoquer l'éjection de gouttelettes de matériau fondu depuis le film donneur sur la surface acceptrice.
