The invention relates to a transverse interconnection low-temperature wafer level packaging method specific to a radio-frequency MEMS (Micro Electro Mechanical System) device application. The method is characterized in that a low-temperature packaging process is performed on a radio-frequency device through a process which combines Au and In isothermal solidification low-temperature bonding with organic material bonding, so that the problem of lead transverse interconnection is solved, and high mechanical strength and airtightness are achieved during packaging at the same time. Meanwhile, a metal deposition way of Au and In isothermal solidification bonding is adopted, namely, Cu is taken as a barrier layer material for an Au and In isothermal solidification reaction, and a thin Au layer is deposited on a surface layer of an In layer to serve as a protection layer material for preventing the In surface layer from being oxidized. The manufacturing of a sealing ring mainly focuses on a packaging cover plate, so that the influence of packaging on the performance of a substrate chip is lowered greatly. Meanwhile, the manufacturing of the sealing ring and the manufacturing of a packaging cavity are integrated in process.
