Claim Text:
1. A device comprising: a MEMS structure over a first substrate, the MEMS structure comprising a movable element; a second substrate over the MEMS structure; a bonding structure interposed between the first substrate and the second substrate, the first substrate, the bonding structure, and the second substrate forming a cavity around the movable element of the MEMS structure; and a TSV extending at least partially through the second substrate, wherein, in a plane parallel to a major surface of the second substrate, the bonding structure has a linear perimeter and a non-linear perimeter protruding from the linear perimeter, the non-linear perimeter of the bonding structure being spaced from an outer perimeter of a projection of the overlying TSV by a constant width.
