Semiconductor device and method of manufacturing thereof

The invention relates to a semiconductor device comprising: a substrate (1), the substrate (1) comprising a body (5), the body (5) having a surface, the substrate (1) being provided with an insulating layer (10) on the surface of the body (1);—a conductor (25) with insulating sidewall spacers (22) located in the insulating layer (10), the conductor (25) having a current-flow direction during operation, the conductor (25) having a first width, the insulating sidewall spacers (22) each having a second width being smaller than the first width of the conductor (25), the first width and the second width being measured in a direction perpendicular to the current-flow direction of the conductor (25) and parallel to said surface, the conductor (25) having a first top surface extending parallel to said surface, the insulating sidewall spacers (22) having a second top surface, and airgaps (30) located in the insulating layer (10) adjacent to the insulating sidewall spacers (22), characterized in that the first top surface coincides with the second top surface, and in that the airgaps (30) extend from the surface of the body (5) to said first and second top surface. The invention further relates to a method of manufacturing such a semiconductor device. The semiconductor device according to the invention enables a lower resistance of the conductor while still providing a tolerance for unlanded vias.

Content delivery network system and method for building the same

A content delivery network system is disclosed. The system comprises a communication network, a first network node for providing services for clients to access network, a second network node for managing hosts for network content providers and a third network node, wherein said third network node sets a default route and a VPN tunnel between the first and second network nodes, and provides a cache server at the bandwidth outlet of the first network node, said cache server stores a information content which has been requested and transmitted. When the client request an information content, the third network node searches the cache server. If the information content is found, the cache server provides said information content to the client directly. If the information content is not found, the cache server sends a request for catching the information content to the second network via the VPN tunnel, and transmits the information content to the client via the default route. The cache server records the data of the transmitted information content. The recorded data is provided to the second network node, so that the second network node can bill the network content provider accordingly.
