  • Patent number: 8763457
    Abstract: A sensing device can be provided with sealed and open-type chambers in various conditions for accommodating different types of sensing structural components by stacking multiple substrates, wherein the condition of a sealed chamber depends on condition taken in substrate bonding process. Owing to sealing a channel of the sealed chamber by the substrate, superior sealing performance is achieved as compared to those adopting solder or sealing material, and thus the condition of the sealed chamber can be finely controlled.
