Abstract: PURPOSE: A method for forming a copper line of a semiconductor device is provided to be capable of preventing the generation of a rounding effect at the upper edge portion of a damascene pattern, for improving the reliability of the device and increasing the degree of integration of the device. CONSTITUTION: A via hole etch stop layer(12), a via hole insulating layer(13), a trench etch stop layer(14), a trench insulating layer(15), and a capping insulating layer(16) are sequentially formed at the upper portion of a substrate(10), wherein the substrate includes a lower copper line(11). After a photoresist pattern is formed at the upper portion of the capping insulating layer, a dual damascene pattern(18) is formed by carrying out an etching process at the resultant structure using the photoresist pattern as an etching mask. Then, the lower copper line is exposed to the outside by selectively etching the via hole etch stop layer. After the photoresist pattern is polished, a post cleaning process is carried out at the resultant structure for completely removing the photoresist residues.

Title: Method and apparatus for receivability test and reachability test of explicit multicast
Inventor: LEE JI UNG
IPC: H04L12/26
Filed: 2002-07-31
Abstract: PURPOSE: A method and system for an explicit multicast receivability test and an explicit multicast reachability test is provided to carry out the explicit multicast receivability test and explicit multicast reachability test of a host in an explicit multicast network without the necessity of adding a new signal packet. CONSTITUTION: A sender end(410) sends a receivability probe packet(400) in order to confirm the explicit multicast receivability test of a receiver end(450). The receivability probe packet(400) arrives at the receiver end(450) through normal unicast routing via generic routers(420-440). In case that the receiver end(450) can understand and receive the receivability probe packet(400), the receiver end(450) passes the received probe packet(400) to an explicit multicast processing block. However, if the receiver end(450) cannot understand or cannot receive the receivability probe packet(400), the receiver end(450) transmits a protocol arrival impossible message to the sender end(410). Based on the protocol arrival impossible message, the sender end(410) confirms that the receiver end(450) has no explicit multicast receivability.
