Paper Abstract

Nowadays surface acoustic wave sensors are produced using a photolithography method. It is expensive in small series production and do not allow further topology correction, which is important for inertial sensors. In this case, a laser ablation method seems promising. It does not require a photomask and can achieve a good matching of topologies produced on opposite sides of the wafer. Several delay lines were produced using a proposed technique. Its characteristics were explored and discussed.
