A copper base alloy, which is resistant or immune to carburization, metal dusting and coking, and resistant to oxidation, the alloy having the following composition : Al >0-15 Si 0-6 Mg 0-6 one or more of the group of Rare Earth Metal, yttrium, hafnium, zirconium, lanthanum, cerium) up to 0. A first dielectric layer separates a bottom and sidewalls of the field plate from the semiconductor region. The insulating protective layer includes a first insulating protective sub-layer formed around the conductive protective layer, the surface thereof being coplanar with the surface of the conductive protective layer, and a second insulating protective sub-layer formed separately from the first insulating protective sub-layer after the conductive bump is formed. An elastic member may be disposed within the clearance in order to prevent the inner rotational shaft from directly contacting the connector sleeve. At least one web service is provided and at least one remote agent is discovered based on at least one web service.
