The new NanoFrazor Explore by Heidelberg Instruments was installed in Polifab. Using an ultra-sharp heatable probe tip capable of both writing and imaging, it allows the creation of complex high-resolution nanostructures in a time efficient way: it represents an alternative to other expensive and complex direct-write methods like electron beam litography.
It is also equipped with a laser writer module for speeding up the coarser patterning, so that both nano- and microfeatures can be quickly written on the same resist in a single fabrication step using the same software platform.
The image below shows a laser-written PoliFab logo complemented with a grayscale (variable height) patterning rendition of the Politecnico di Milano logo, demonstrating the probe tip writing capabilities.
