COMPONENT AND METHOD FOR MANUFACTURE

A component (10) includes a substrate (15), a cap wafer (23), and a protection layer (28) formed over a surface of the cap wafer (23). Together, the protection layer (28) and the cap wafer (23) form a cap structure (39) that is bonded to the substrate (15) via a bonding layer (33). An opening (47) i...

Zusammenfassung:A component (10) includes a substrate (15), a cap wafer (23), and a protection layer (28) formed over a surface of the cap wafer (23). Together, the protection layer (28) and the cap wafer (23) form a cap structure (39) that is bonded to the substrate (15) via a bonding layer (33). An opening (47) is formed in the cap wafer (23) by etching the cap wafer (23). The protection layer (28) provides protection during etching of the cap wafer (23) for the underlying bonding layer (33) and devices (11,12) formed in the substrate (15).
