摘要：
This paper introduces a novel wafer-level hermetic packaging technology for MEMS based on Cu/Sn isothermal solidification (IS) technology We designed the structure of the intermediate multi-layer and the pattern of sealing rings, optimized the bonding process, and analyzed some key factors affecting the hermeticity, such as the dimension of the sealing rings. Successful Cu/Sn IS bonding was realized at a low bonding temperature of 350 degrees C under the optimal conditions. High shear strength of 27.7MPa and excellent leak rate of around 2 X 10(-9)atm cc/s have been achieved, which meet the requirements of MIL-STD-883E. Finally we designed and manufactured the micro resonator based on the Cu/Sn IS technology.
