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.

Claim (Index 1):
A microelectromechanical system (MEMS) device comprising\n a first substrate including an active surface, wherein the active surface further includes a first electric-conduction contact, at least one second electric-conduction contact, at least one third electric-conduction contact, and a fixed electrode; a second substrate including a first surface, a second surface opposite to the first surface, a first bonding portion, at least one second bonding portion, and a movable element, wherein the first bonding portion and the second bonding portion are disposed on the first surface of the second substrate; the first bonding portion surrounds the movable element; the second bonding portion is disposed between the first bonding portion and the movable element; the first boding portion and the second bonding portion of the second substrate are respectively bonded to the first electric-conduction contact and the second electric-conduction contact of the first substrate to make the movable element corresponding to the fixed electrode and make the first substrate, the second substrate and the first bonding portion jointly define an airtight chamber; and a metal getter disposed between the second bonding portion and the second electric-conduction contact, and extended outward.
