MicroWriter ML3 Baby
Durham Magneto OpticsMicroWriter ML®3 Baby is a compact, high-performance, low-cost direct-write optical lithography machine which is designed to offer unprecedented value for money in a small laboratory footprint. Measuring only 70cm x 60cm at its base, it sits on a standard laboratory bench or desk and plugs into a supplied laptop computer. Its only service requirement is a standard power socket. A light-excluding enclosure with safety interlock allows it to be used equally well in an open laboratory environment or in a clean room. Easy to use Windows® based software means most exposures can be set up and launched with just a few mouse clicks.
Features and Specifications• 149mm x 149mm maximum writing area.
• 155mm x 155mm x 7mm maximum wafer size.
• 1µm minimum feature size across full writing area.
• 405nm long-life semiconductor lightsource suitable for broadband, g- and h-line positive and negative photoresists (e.g. S1800, ECI-3000, MiR 701). Replacement 385nm and 365nm lightsources available as option, suitable for g-, h- and i-line photoresists (e.g. SU-8).
