Method for fabricating a gyroscope including: fabricating a SMS wafer where a first wafer, a metal film, and a second wafer are sequentially stacked; forming a cantilever or a bridge shaped-structure on the relevant portion of the first wafer through the photolithography process; attaching to the surface of the first wafer, a first cap made of glass and having a predetermined space for sealing the movable structure in a vacuum state; separating and removing the metal film and the second wafer from the first wafer; and attaching to the backside of the first wafer, the second cap which is structurally and materially symmetric to the first cap. The SMS wafer is fabricated by depositing the metal film on the second wafer and bonding the first wafer on the metal film using metal paste or material of polymer series. With lower material costs, improvements in performance and characteristics can be achieved. |
