The SAW delay lines consist of Al inter-digital transducers (IDT) on LiNbO3 substrate. It is designed with specific IDT feature size to produce SAW at predetermined central frequency, f0. The effect of the etching process onto the IDT, in particular the feature size, is investigated using field emission secondary electron microscope (FESEM). The effect is then translated into transfer characteristics of the SAW delay lines by measuring its transmission and reflection coefficient using network analyzer. It is found that even with a �5 μm IDT feature size variation due to the wet chemical etching process, the fabricated delay lines can still produce SAW at the designed f0, and hence a process-tolerant SAW delay lines. © 2012 IEEE.
