Patent ID: 7867874

Claim:
A method comprising: providing a wafer comprisng: a first side; a second side; a plurality of sections disposed on the first side; and a plurality of first annular surface portions disposed on a respective one of the plurality of sections; forming a plurality of spaced structures on the first side of the wafer in a manner so that each of the structures is on a respective one of the sections, and so that each of the first annular surface portions extends around a respective one of the spaced structures; providing a cover, the cover having on one side thereof a plurality of second annular surface portions which are each engageable with a respective one of the first annular surface portions; bonding each of the first annular surface portions to a respective one of the second annular surface portions to create a plurality of hermetically sealed chambers between the wafer and the cover, each hermetically sealed chamber having therein a respective one of the structures; creating an opening through the wafer that extends from the first side to the second side; and forming a via within the opening, the via operable to provide a hermetic seal within the opening with respect to the first and second sides of the wafer, the via comprising: a first end adjacent to the first side of the wafer; a second end adjacent to the second side of the wafer; a conductive portion operable to provide electrical conductivity between the first end and the second end; forming a sleevelike portion with an electrically conductive material within the via; and forming an electrically non-conductive core portion within the sleevelike portion.
