摘要

Passivation layers consisting of sputtered Al2O3n have been deposited onto SAW devices for the purpose of reducingnthe incidence of shorts. A coupling-of-modes model was used withnone-port resonators, coupled resonator filters (CRF), and testnstructures. The passivation layer stiffens the surface with a velocitynincrease proportional to t/Λ, where t is the passivation layernthickness. Attenuation is increased slightly, producing a 0.25-dBnincrease in the loss of a one-port resonator at 314 MHz. The effect onnreflectivity is minimal and of much lesser importance to the designer
