  • Patent number: 10910185
    Abstract: The present invention is directed to a method for the fabrication of electron field emitter devices, including carbon nanotube (CNT) field emission devices. The method of the present invention involves depositing one or more electrically conductive thin-film layers onto an electrically conductive substrate and performing lithography and etching on these thin film layers to pattern them into the desired shapes. The top-most layer may be of a material type that acts as a catalyst for the growth of single- or multiple-walled carbon nanotubes (CNTs). Subsequently, the substrate is etched to form a high-aspect ratio post or pillar structure onto which the previously patterned thin film layers are positioned. Carbon nanotubes may be grown on the catalyst material layer. The present invention also described methods by which the individual field emission devices may be singulated into individual die from a substrate.

  • Patent number: 10109789
    Abstract: Disclosed herein are methods for additive formation of a STT-MRAM metal stack using a deposition process through a pre-patterned template that skims away metal ions that are less likely to enable anisotropic deposition on a substrate. The pre-patterned template is formed from a film stack using patterning techniques to form an opening in the film stack that exposes portions of an underlying substrate where a MTJ will be formed for an MRAM cell. The film stack cavity may be exposed to etch processes that selectively pull back the sidewall, such that other layers in the film stack protrude into the cavity. Additional treatments to the other layers may alter the opening sizes in the other layers. Metal deposited through the cavity such that metal ions with anisotropic characteristics will be skimmed away before reaching the substrate.

  • Patent number: 9941088
    Abstract: A field emission transistor includes a gate, a fold over emitter, and fold over collector. The emitter and the collector are separated from the gate by a void and are separated from a gate contact by gate contact dielectric. The void may be a vacuum, ambient air, or a gas. Respective ends of the emitter and the collector are separated by a gap. Electrons are drawn across gap from the emitter to the collector by an electrostatic field created when a voltage is applied to the gate. The emitter and collector include a first conductive portion substantially parallel with gate and a second conductive portion substantially perpendicular with gate. The second conductive portion may be formed by bending a segment of the first conductive portion. The second conductive portion is folded inward from the first conductive portion towards the gate. Respective second conductive portions are generally aligned.

  • Patent number: 9911568
    Abstract: A metal jet x-ray tube is proposed, that is affected less than conventional tubes by the problem of the power density at the point of incidence of the electron beam on the anode component. To this end, the metal jet x-ray tube provides a metal jet as an anode component that is so thin that this metal jet only partly decelerates an electron beam incident thereon. Moreover, the metal jet of the anode component is at least embedded or dissolved in a single second material that passes electrons relatively well and is heat absorbing.

  • Patent number: 9852870
    Abstract: The present invention is directed to a method for the fabrication of electron field emitter devices, including carbon nanotube (CNT) field emission devices. The method of the present invention involves depositing one or more electrically conductive thin-film layers onto a electrically conductive substrate and performing lithography and etching on these thin film layers to pattern them into the desired shapes. The top-most layer may be of a material type that acts as a catalyst for the growth of single- or multiple-walled carbon nanotubes (CNTs). Subsequently, the substrate is etched to form a high-aspect ratio post or pillar structure onto which the previously patterned thin film layers are positioned. Carbon nanotubes may be grown on the catalyst material layer. The present invention also described methods by which the individual field emission devices may be singulated into individual die from a substrate.
