Electron-beam lithography is the practice of scanning a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive film called a resist (exposing). — Wikipedia

We can probably do electron-beam lithography on our Zeiss DSM "Kevin". A major component for making this work is a beam-blanker which we already have (#35).

Sam Zeloof has explored this topic as well (Blog) and noted that standard photoresists seem to work reasonably well. Beyond that, there are special e-beam resists, but they may be hard to acquire.
