Abstract: The present invention relates to a method for manufacturing an inductor being a passive device in RE MEMS, RFCMOS, Bipolor/SiGe and BiCMOS semiconductor devices. According to the present invention, a first negative photoresist layer is covered on a substrate having a lower electrode. A via hole that will become a contact portion of the inductor is then defined by means of an exposure process using a first mask. A second negative photoresist layer is covered on the first negative photoresist layer. Trenches that will become line portions of the inductor are defined by an exposure process using a second mask. A damascene pattern having the via hole and the trenches is formed by means of a developing process and is then buried with copper, thus forming the inductor. Not only a thickness of the trenches in the line portion and a thickness of the via hole in the contact portion can be uniformly controlled, but also their height can be easily controlled.

Abstract: A method of advertising an address of a domain name service (DNS) server present, for example, on an IPv6 network by searching a location of the DNS server on a router network subnet using a dynamic routing protocol, storing link state information of the router indicating the DNS server existence in the router subnet, in a link state advertisement of the router, and delivering the link state advertisement to all routers within an autonomous system, to which the router belongs. When the router having the location of the DNS server is requested by another router to provide the DNS server address, the router replies to the requesting router, and the requesting router receiving the reply, advertises a router advertisement message containing the DNS server address to a subnet to which the requesting router belongs. Accordingly, a network can be set without manually setting DNS server addresses at hosts.

Abstract: A method and a system of automatically creating and registering a domain name and an IP address in an IPv6 (IP version 6) network are provided. According to the method of automatically registering a domain name, name information of a network including a host is received. A link local address of the host is created and it is determined whether the created link local address has already been used. If the created link local address has not been used, an interface ID used to determine the host is extracted from the created link local address. A domain name is created using the extracted interface ID and the received name information of the network. The created domain name is registered in a domain name server.
