Title:
SURFACE ACOUSTIC WAVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/096015
Kind Code:
A1
Abstract:
SAW devices (100) and methods of fabricating SAW devices (100) are disclosed. The disclosed SAW device (100) includes a piezoelectric layer (204). The SAW device (100) also includes at least one transducer (104,106) coupled to the piezoelectric layer (204). The transducer (104,106) includes a first set of electrodes and a second set of electrodes. Each electrode(116,118) in the first set of electrodes is directly adjacent to at least one electrodes(116,118) in the second set of electrodes along a wave propagation axis x, and the first and second set of electrodes are separated from each other along a depth axis z.
