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 13):
A method for manufacturing a microelectromechanical system (MEMS) device, comprising steps as following:\n providing 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; providing a second substrate including a first surface and a second surface opposite to the first surface; forming a groove on the first surface or the second surface of the second substrate to define a movable element; forming a first bonding portion and at least one second bonding portion on the first surface of the second substrate, wherein the first bonding portion surrounds the movable element, and the second bonding portion is disposed between the first bonding portion and the movable element, and wherein a bonding surface of the first bonding portion is larger than a bonding surface of the second bonding portion; disposing a bonding material on the first bonding portion, and disposing a metal getter on the bonding surface of the second bonding portion; bonding the first substrate to the second substrate, wherein the first bonding portion is bonded to the first electric-conduction contact, and the second bonding portion is bonded to the second electric-conduction contact, to make the first substrate, the second substrate and the first bonding portion jointly define an airtight chamber and squeeze the metal getter on the second bonding portion out of the bonding surface of the second bonding portion; and activating the metal getter to absorb a moisture in the airtight chamber.
