Smallest geez alphabets inscribed on silicon wafers

These are possibly the smallest 'geez fidel' inscriptions your eyes have ever seen. The image has been taken using a scanning electron microscope from the cleanest facility in Spain located at Universitat Autonoma de Barcelona (UAB) in 2010.

You can think of the area to be equivalent to the tip of your pen and this is fabricated using nano and microfabrication techniques on a silicon wafer.

Thanks to Mesfin Agidie who created the fonts in his Abinet typing software. I did the tedious task of designing each of the above alphabets point by point on a specialized patterning software which dictates the etching machine.

Special thanks to Prof. Francesc Perez Murano and Prof. Xavier Borrisie
