1. A method for manufacturing a component, comprising:
- providing a substrate having interconnect formed thereon;
providing a cap wafer;
disposing a protection layer over a surface of the cap wafer;
disposing a bonding layer over a portion of the protection layer;
using the bonding layer for attaching the cap wafer and protection layer to the substrate; and
forming an opening in the cap wafer and protection layer to expose the interconnect on the substrate after attaching the protection layer to the substrate.

Abstract
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).

8. A method for manufacturing a component, comprising the steps of:
-
bonding a cap to a substrate using a bonding material to form a hermetically sealed cavity, wherein the hermetically sealed cavity is formed by the bonding material, the cap and the substrate, the substrate has an interconnect layer formed thereon, and bonding material is frit glass; and
forming an opening in the cap after bonding the cap to the substrate to expose the interconnect layer. - View Dependent Claims (9, 10, 11)
