A method for the fabrication of surface acoustic wave devices by the selective removal of one of the phases of a metallic eutectic, solidified as a thin film having a lamellar morphology, forms a first spaced array of metallic elements. Removal is by line-heater or laser beam. This then provides a self-aligned structure for the formation of a second array of metallic elements interdigitated with the elements of the first array.
