bonding. These surface-micromachined structures are so sensitive and fragile that they require a protection cap in order to survive the dicing and assembly process. Yet most of the established bonding technologies cannot be used for such systems: (1) Anodic bonding of whole glass wafers is not suitable because the glass.

Annealing in the electric field (anodic bonding) provides a very high bonding strength, close to the mechanical strength of the initial bulk materials. Anodic bonding efficiency is associated with the high mobility of alkali ions at high temperature. The movement of ions is controlled by an electric field. However alkali atoms are.
