H01J 37/073 H01J 37/22 G01N 23/20058
Abstract:
The system includes a photocathode electron source, diffractive optical element, and a microlens array to focus the beamlets. A source directs a radiation beam to the diffractive optical element, which produces a beamlet array to be used in combination with a photocathode surface to generate an array of electron beams from the beamlets.

International Classification:
H01J 1/34 H01J 37/317 G02B 5/00
Abstract:
A photocathode emitter can include a transparent substrate, a photocathode layer, and a plasmonic structure array disposed between the transparent substrate and the photocathode layer. The plasmonic structure can serve as a spot-confining structure and an electrical underlayer for biasing the photocathode. The plasmonic structure can confine the incident light at subwavelength sizes.

A photocathode can include a body fabricated of a wide bandgap semiconductor material, a metal layer, and an alkali halide photocathode emitter. The body may have a thickness of less than 100 nm and the alkali halide photocathode may have a thickness less than 10 nm. The photocathode can be illuminated with a dual wavelength scheme.

International Classification:
H01J 1/34 H01J 37/28
Abstract:
A photocathode structure, which can include one or more of CsTe, CsKTe, CsI, CsBr, GaAs, GaN, InSb, CsKSb, or a metal, has a protective film on an exterior surface. The protective film includes one or more of ruthenium, nickel, platinum, chromium, copper, gold, silver, aluminum, or an alloy thereof. The protective film can have a thickness from 1 nm to 10 nm. The photocathode structure can be used in an electron beam tool like a scanning electron microscope.
High Brightness Boron-Containing Electron Beam Emitters For Use In A Vacuum Environment
- Milpitas CA, US Gildardo R. Delgado - Livermore CA, US Frances Hill - Sunnyvale CA, US Edgardo Garcia Berrios - San Jose CA, US Rudy Garcia - Union City CA, US
International Classification:
H01J 1/304 H01J 19/24 H01J 1/34 H01J 9/02
Abstract:
An emitter containing a metal boride material has an at least partly rounded tip with a radius of 1 μm or less. An electric field can be applied to the emitter and an electron beam is generated from the emitter. To form the emitter, material is removed from a single crystal rod to form an emitter containing a metal boride material having a rounded tip with a radius of 1 μm or less.
