    • A MEMS package of device and a manufacturing method thereof are provided to increase the degree of freedom for interconnection layout by using bumps as bonding bumps, sealing lines and alignment bumps. A MEMS package comprises a cap wafer, and a plurality of bonding bumps formed on the cap wafer. A plurality of alignment bumps are formed at the outer sides of the bonding bumps. A wafer for a MEMS device has a plurality of first external pads corresponding to the alignment bumps. When the wafer is bonded to the cap wafer, the alignment bumps are bonded to the first external pads. Sealing lines are formed between the bonding bumps and the alignment bumps to surround the bonding bumps, wherein the bonding bumps and the sealing lines are formed on the same layer.
    • 提供了MEMS封装的器件及其制造方法,以通过使用凸块作为接合凸块,密封线和对准凸块来增加互连布局的自由度。 MEMS封装包括盖晶片和形成在盖晶片上的多个焊接凸块。 在接合凸块的外侧形成有多个对准凸块。 用于MEMS器件的晶片具有对应于对准凸块的多个第一外部焊盘。 当晶片结合到盖晶片时,对准凸块接合到第一外部焊盘。 密封线形成在接合凸块和对准凸块之间以包围接合凸块,其中接合凸块和密封线形成在同一层上。
