MicroWriter ML3 Baby Plus

Durham Magneto Optics

The Baby Plus is our top selling machine and adds a number of features to the Baby which are usually only found in high-end machines. Two different resolutions (1μm and 5μm) can be selected automatically via software and without the user needing to exchange any lens manually. This allows non-critical parts of the exposure to be performed rapidly at 5μm resolution while retaining high resolution writing for critical parts. Locating alignment markers or edges of substrates is faster thanks to an automatic lens changer on the optical microscope allowing the user to switch between x3 and x10 objectives via software. The MicroWriter ML®3 Baby Plus also features an optical surface profilometer tool and an automated wafer inspection tool for examining fabricated structures. As with all of our machines, writing speeds are some of the fastest on the market: up to 20mm2/minute at 1μm resolution and up to 120mm2/minute at 5μm resolution, allowing a typical 50mm x 50mm area combining critical and non-critical areas to be exposed in under 30 minutes.
