The invention relates 'to a micro X-ray source comprising a target acting as anode, and a cathode, which during operation interacts with the target and functions as electron source, wherein the target is embodied as a metal foil possessing a spot where the electrons from the electron source arrive, the metal foil being locally thinner at the spot.

The potential application of carbon nanotubes as electron sources in electron microscopes is analyzed. The resolution and probe current that can be obtained from a carbon nanotube emitter in a low-voltage scanning electron microscope are calculated and compared to the state of the art using Schottky electron sources. Many analytical equations...

Electron-beam-induced deposition (EBID) is a versatile micro- and nanofabrication technique based on electron-induced dissociation of metal-carrying gas molecules adsorbed on a target. EBID has the advantage of direct deposition of three-dimensional structures on almost any target geometry. This technique has occasionally been used in focused...

Lithography system comprising a light source producing a light beam directed to a mask (3) located in a mask level and an optical demagnifier (4-6) for demagnifying by a factor and focusing the beam. The light beam is focused on a converter element (8) for converting said beam in a further beam having a smaller wavelength than UV light. The beam...
