Cross-sections of laser fabricated nanosharp tips and microbumps on silicon and metal thin
films are produced and examined in this work. These structures are formed with a Q-
switched neodymium doped yttrium aluminum garnet nanosecond-pulse laser, emitting at its
fourth harmonic of 266 nm, using a mask projection technique to generate circular laser
spots, several microns in diameter. Cross-section of selected structures were produced
using a focused ion beam and were characterized via electron microscopy. The diffraction …
