Abstract
Microfabrication of sub-micron holes on 30 nm thick aluminum films on fused silica was investigated using pulse durations from 300 fs to 6 ns at 400 nm wavelength. Micromachines areas were investigated using atomic force microscopy (AFM) for quality and size of features produced. Ablation diameters less than 400 nm was achieved with all pulse widths. Pulses less than 5 ps removed the films cleanly and left a flat-bottomed crater with no evidence of substrate melting over a wide fluence range.
