The nanostructuring of dielectrics is a big challenge for laser patterning methods. In this study a novel laser structuring method for the fabrication of randomly distributed nanostructures, called laser-induced front side etching using in situ pre-structured metal layers (IPSM-LIFE), is presented. The pulsed laser irradiation of a thin metal film deposited onto a dielectric substrate with fluences below the ablation threshold results in the formation of randomly distributed metal structures by self-assembly processes. Further pulsed laser irradiation of these metal structures with higher or equal laser fluences causes the formation of complex patterns at the surface of the dielectric due to localized ablation and melting processes of the dielectric surface induced by the absorption of the laser energy by the metal structures and the local energy transfer into the dielectric surface.The pattern formation observed in the film and the dielectrics substrate after irradiation of 10 nm chromium layers on fused silica, with laser pulses (Δtp=25 ns,λ=248 nm), was studied by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Different features with a lateral size down to a few tens of nanometers, like concentric ring patterns, donut-like structures, and bar patterns were observed at the dielectric.
