ABSTRACT:
In a surface acoustic wave transducer having closely space-apart IDT electrode segments, a metallic oxide is selectively formed only along the marginal edge of each electrode segment so that it separates adjacent electrode segments, thereby preventing short-circuiting therebetween, permitting easy fabrication of the transducer and improving the yield rate of fabrication.
