Abstract: The present disclosure relates to the field of semiconductor technologies, and discloses a method for manufacturing a semiconductor apparatus. The method includes: forming a water film on a bottom surface of a top wafer and a top surface of a bottom wafer; after the water film is formed, attaching the bottom surface of the top wafer to the top surface of the bottom wafer; disposing the attached top wafer and bottom wafer in a vacuum environment; and performing a thermal annealing process, so that the bottom surface of the top wafer is fusion-bonded to the top surface of the bottom wafer. The disclosed methods can reduce bubble voids existing between the bonded wafers.

Abstract: The present disclosure provides bond pad structures, boning ring structure; and MEMS device packaging methods. An exemplary bonding pad structure includes a plurality of first metal blocks made of a first metal material; and a plurality of second metal blocks made of a second metal material. The plurality of first metal blocks are used to prevent the squeezing out and extending of the plurality of second metal blocks. On at least one equal dividing plane of the bonding pad structure, the first metal material is shown at least one time; and the second metal material is shown at least one time.
