Surface acoustic wave device with electro-static discharge protection |
摘要 |
Sacrificial electrodes with fractal-shaped are formed on a SAW (surface acoustic wave) device. The sacrificial electrodes discharge electro-static charge in the SAW device for protecting the IDT (inter-digital transducer) from electrostatic break. Moreover, the sacrificial electrodes can control the path and the discharging degree of the electro-static discharge to avoid losing the electrostatic discharge protection due to the sacrificial electrodes are broken.
