Gas assisted focused electron beam induced etching of alumina

Patrik Willi Hoffmann, Tristan Bret, Bamdad Afra

This study investigates focused electron beam induced etching for the removal of alumina particles on patterned extreme ultra violet (EUV) mask using nitrosyl chloride (NOCl) as assist gas. As potential contaminant, particles of aluminum oxide (alumina, Al ...

Submicrometer Hall devices fabricated by focused electron-beam-induced deposition

Radivoje Popovic, Giovanni Boero, Patrik Willi Hoffmann, Pavel Kejik, Niels Quack, Tristan Bret, Jürgen Brugger, Schahrazede-Lila Mouaziz

Hall devices having an active area of about (500 nm)(2) are fabricated by focused electron-beam-induced deposition. The deposited material consists of cobalt nanoparticles in a carbonaceous matrix. The realized devices have, at room temperature, a current ...

Physico-chemical study of the focused electron beam induced deposition process

Tristan Bret

The focused electron beam induced deposition process is a promising technique for nano and micro patterning. Electrons can be focused in sub-angström dimensions, which allows atomic-scale resolution imaging, analysis, and processing techniques. Before the ...
