摘要:
A method is disclosed for creating an emitter having a flat cathode emission surface: First a protective layer that is conductive is formed on the flat cathode emission surface. Then an electronic lens structure is created over the protective layer. Finally, the protective layer is etched to expose the flat cathode emission surface.
摘要:
A vacuum device, including a substrate and a support structure having a support perimeter, where the support structure is disposed over the substrate. In addition, the vacuum device also includes a non-evaporable getter layer having an exposed surface area. The non-evaporable getter layer is disposed over the support structure, and extends beyond the support perimeter, in at least one direction, of the support structure forming a vacuum gap between the substrate and the non-evaporable getter layer increasing the exposed surface area.

This disclosure relates to systems and methods for reducing feature sizes. One of these methods enables formation of an original feature having a size in a length or width dimension of between about 100 and about 1000 nanometers with a system capable of patterning features to a minimum size of less than or about the size of the original feature and reduction of the size of the original feature below that of the minimum size of the system using an alignment-independent technique.
摘要:
An emitter has an electron supply and a porous cathode layer having nanohole openings. The emitter also has a tunneling layer disposed between the electron supply and the cathode layer.
摘要:
A MEMS device includes at least one movable member and an active device having at least one property affected by the location of the movable member with respect to the active device. A control circuit is used to limit movement of the movable member based on observation of the property affected by the active device.
摘要:
An emitter includes an electron supply and a tunneling layer disposed on the electron supply. A cathode layer is disposed on the tunneling layer. A conductive electrode has multiple layers of conductive material. The multiple layers include a protective layer disposed on the cathode layer. The conductive electrode has been etched to define an opening thereby exposing a portion of the cathode layer.

摘要:
A light device includes an electron supply defining an emitter surface. A dielectric tunneling layer is disposed between the electron supply and a cathode layer. The cathode layer has at least partial photon transparency that is substantially uniform across the emitter surface.
摘要:
An emitter has an electron supply layer and a tunneling layer formed on the electron supply layer. Optionally, an insulator layer is formed on the electron supply layer and has openings defined within in which the tunneling layer is formed. A cathode layer is formed on the tunneling layer. A conductive layer is partially disposed on the cathode layer and partially on the insulator layer if present. The conductive layer defines an opening to provide a surface for energy emissions of electrons and/or photons. Preferably but optionally, the emitter is subjected to an annealing process thereby increasing the supply of electrons tunneled from the electron supply layer to the cathode layer.
