Latest Patents
Ahn's latest patents include a micro-electron column featuring an electron emitter that improves the density of an electron beam emitted from a nanostructure tip. This invention discloses a micro-electron column that incorporates nanostructure tips, which can easily emit electrons due to the high electric field generated at their ends when a voltage is applied. The design includes an induction electrode positioned between the electron emitter and a source lens, facilitating the entry of emitted electrons into the aperture of the first lens electrode layer, thereby enhancing the micro-electron column's performance.
Another notable patent is the multi-particle beam column that includes an electrode layer with eccentric apertures. This invention comprises two or more particle beam columns, each equipped with a particle beam emission source, a deflector, and multiple electrode layers. The unique feature of this design is that at least one electrode layer has one or more apertures that are eccentric from the respective beam optical axes of the particle beam columns.
