Highly textured Al[111] films have been grown on an ultrathin metal underlayer by ion-beam sputtering technique regardless of substrate material and its cutting angle. Surface acoustic wave filters with the highly textured Al[111] electrodes were fabricated and the power durability was investigated. They have lifetimes more than 3000 times longer than those with evaporated polycrystalline Al electrodes.
