Abstract: To improve the performance and reliability of micro-electro-mechanical system (MEMS) devices, MEMS wafer-level packaging technology has become the shortcut to break through the bottleneck of MEMS device practicality. Wherein, MEMS wafer-level packaging based on wafer bonding has attracted much attention in the industry and academia owing to its low packaging temperature, high freedom in packaging structures and processes, and high structural reliability. The main functions and classifications of MEMS wafer-level packaging are summarized, and the advantages of MEMS wafer-level packaging technology based on wafer bonding are clarified. MEMS wafer-level packaging approaches based on wafer bonding, which can be divided into two types of the planar interconnection and the vertical interconnection, are reviewed with illustrations of technical backgrounds, packaging strategies, advantages/disadvantages, and limitations. The current situation of MEMS wafer-level packaging is summarized, and the future development trend is prospected.

Key words: wafer bonding, micro-electro-mechanical system, wafer-level packaging, planar interconnection, vertical interconnection
