    摘要: A disclosed semiconductor fabrication process includes forming a first bonding structure on a first surface of a cap wafer, forming a second bonding structure on a first surface of a device wafer, and forming a device structure on the device wafer. One or more eutectic flow containment structures are formed on the cap wafer, the device wafer, or both. The flow containment structures may include flow containment micro-cavities (FCMCs) and flow containment micro-levee (FCMLs). The FCMLs may be elongated ridges overlying the first surface of the device wafer and extending substantially parallel to the bonding structure. The FCMLs may include interior FCMLs lying within a perimeter of the bonding structure, exterior FCMLs lying outside of the bonding structure perimeter, or both. When the two wafers are bonded, the FCMLs and FCMCs confine flow of the eutectic material to the region of the bonding structure.

    摘要: A method (50) for producing a layered wafer structure (24) having anti-stiction bumps (22) entails producing the anti-stiction bumps (22) in a surface (32) of a substrate (26) or, alternatively, in a surface (48) of a substrate (28). The method (50) further entails coupling the substrates (26, 28) with an insulator layer (30) interposed between the substrates (26, 28). A MEMS structure (20) having a movable element (34) is formed in the substrate (28) and openings (78) defining the movable element (34) extend through the substrate (28). A portion of the insulator layer (30) is removed via the openings (78) to release the movable element (34). The anti-stiction bumps (22) limit stiction between the movable element (34) and the underlying substrate (26).

    摘要: A device structure is made using a first conductive layer over a first wafer. An isolated conductive region is formed in the first conductive layer surrounded by a first opening in the conductive layer. A second wafer has a first insulating layer and a conductive substrate, wherein the conductive substrate has a first major surface adjacent to the first insulating layer. The insulating layer is attached to the isolated conductive region. The conductive substrate is thinned to form a second conductive layer. A second opening is formed through the second conductive layer and the first insulating layer to the isolated conductive region. The second opening is filled with a conductive plug wherein the conductive plug contacts the isolated conductive region. The second conductive region is etched to form a movable finger over the isolated conductive region. A portion of the insulating layer under the movable finger is removed.
