  • Patent number: 10748734
    Abstract: An efficient source of EUV or SXR flux uses multiple e-beams from multiple cathodes to impact a wide anode target with a flux-generating surface to generate flux over a wide area. The conversion efficiency of e-beam power to flux power may be improved by the direction of the e-beams towards the anode target at shallow or grazing incidence angles or the use of mirrored anode surfaces which reflect EUV or SXR. The source is enclosed in a vacuum chamber and performs work such as the penetration of photoresist on a semiconductor wafer in vacuum.
    Type: Grant

  • Patent number: 9508523
    Abstract: This invention provides a source of x-ray flux in which x-rays are produced by e-beams impacting the inner walls of holes or channels formed in a metal anode such that most of the electrons reaching the channel impact an upper portion of said channel. A portion of the electrons from this primary impact will generate x-rays. Most of the electrons scatter but they continue to ricochet down the channel, most of them generating x-rays, until the beam is spent. A single channel source of high power efficiency and high power level x-rays may be made in this way, or the source can be of an array of such channels, to produce parallel collimated flux beams of x-rays.

  • Patent number: 9242019
    Abstract: A pipe source of UV flux has an inner pipe made of UV transmissive material and coated on its outer surface with a UV emitting phosphor. An outer pipe has a cathode array disposed on or near its inner surface, such as an array of thermionic filament cathodes mounted longitudinally or transverse to the length of the pipe, cold cathode arrays formed on the inner surface of the pipe or cold cathode arrays formed on separate substrates which are then attached to the inner surface of the outer pipe. The ends of this two-pipe assembly are hermetically sealed with flanges or end plates at either end of the pipe and evacuated to a pressure below 1×10?3 Torr. Internal spacing rings may be used to provide additional separation between the inner and out pipes. Current from the cathode arrays is accelerated by an anode voltage to strike the UV phosphors when then emit UV light flux which illuminates the inside of the pipe and the fluid material flowing through the inner pipe.

  • Publication number: 20150262779
    Abstract: A flat panel UV source emits UV flux from one or more phosphor materials disposed on an anode plate and excited by electron beam current accelerated in vacuum toward the anode from one or more arrays of thermionic filament cathodes. The filament cathode arrays may be constructed and held in one or more cathode frames attached to or near a cathode plate. Increasing the number of these frames allows scaling of the areal size of the source, since the frames are constructed so as to allow for sag of the filaments as they are heated and cooled during operation.

  • Publication number: 20130272503
    Abstract: A radiation source which can emit X-ray flux using electron beam currents from a cathode array formed on the window through which the radiation will exit the source. The source can be made in formats which are compact or flat compared with prior art radiation sources. X-ray flux produced by the source can be used for such purposes as radiation imaging, sterilization, decontamination of biohazards or photolithography.

  • Patent number: 6607930
    Abstract: A method for fabricating a thin-film edge emitter device includes the steps of providing a first conductive layer having a top surface; providing an insulating layer having a top surface disposed above the top surface of the first conductive layer; providing a second conductive layer on the insulating layer; and providing a well in the insulating layer over the first conductive layer and an edge in the second conductive layer proximate the well. Providing the well and the edge includes processing the first conductive, insulating, and second conductive layers by at least one of lift-off processing, photolithography processing, and processing with the use of a pre-formed insulating layer having at least one opening associated with a location of the well. The first conductive layer forms an anode. Lastly, the second conductive layer forms at least one of a cladded cathode having an emissive edge and a control electrode.
