ANU-1 is a maskless optical lithography tool built on Nabu's parallel thermal projection platform. It writes patterns directly from a virtual mask, so chip designers can prototype and move into mid-volume production on the same tool, with no photomask cost or lead time.

01
No photomask
Designs load as a virtual mask from GDSII or OASIS. A design change goes from file to wafer with no re-tooling.
Thermal resist
Thermally activated resists give sub-wavelength features and immunity to beam imperfections, for higher resolution and yield.
Parallel writing
Massively parallel laser writing is up to 100× faster than conventional direct laser writers. Write speed does not depend on design complexity or resolution.
Fits standard cleanroom processes
Resist is deposited by standard DC or RF sputtering. Developing, etching and lift-off work just as they do with conventional photoresist.
Verify before developing
Patterns can be checked before the wafer is developed. On transparent substrates, features are visible in real time during writing.
Simple facility requirements
No yellow-light room, three-phase power, nitrogen line or water line is required.
