Description

The surface morphology of polymethylmethacrylate (PMMA) samples bombarded with size-selected Ar cluster ion beam (1000-16000 atoms/cluster) was investigated. The incident cluster ion size was selected before irradiation by using the time-of-flight (TOF) method. The irradiation ion fluence was 2 x 1013 -1 x 1014 ions/cm2. The average surface roughness values measured by AFM after 25 nm etching with 20 keV Ar1000+ and Ar16000+ were 4.0±0.4 and 0.78±0.09 nm, respectively. Thus, large clusters would be suitable for low damage etching. (author)
