Abstract: A method for manufacturing a MEMS device includes disposing at least one bonding portion having a smaller bonding area in a region where an airtight chamber will be formed, and disposing a metal getter on a bonding surface of the bonding portion. According to this structure, when substrates are bonded to define the airtight chamber, the metal getter is squeezed out of the bonding position due to the larger bonding pressure of the bonding portion with a smaller bonding area. Then, the metal getter is activated to absorb the moisture in the airtight chamber. According to the above process, no additional procedure is needed to remove the moisture in the airtight chamber. A MEMS device manufactured by the above manufacturing method is also disclosed.
