TEM specimens of a LaAlO3/SrTiO3 multilayer are prepared by FIB with internal lift out and it is observed that the LaAl O3 layers are preferentially destroyed and transformed into amorphous material, during the thinning process. TEM specimens of a LaAlO3/SrTiO3 multilayer are prepared by FIB with internal lift out. Using a Ga+1 beam of 5 kV, a final cleaning step yielding top, top‐angle ...
WhatsApp: +86 18203695377Abstract. The semiconductor industry recently has been investigating new specimen preparation methods that can improve throughput while maintaining quality. The result has been a combination of focused ion beam (FIB) preparation and ex situ liftout (EXLO) techniques. Unfortunately, the carbon support on the EXLO grid presents problems if the lamella needs to be thinned once it is on the grid ...
