    摘要: A MEMS is attached to a bonding wafer in part by forming a support layer over the MEMS. A first eutectic layer is formed over the support layer. The eutectic layer is patterned into segments to relieve stress. A second eutectic layer is formed over the bonding wafer. A eutectic bond is formed with the segments and the second eutectic layer to attach the bonding wafer to the MEMS.
