Abstract: PURPOSE: An improved method for fabricating a storage electrode of a semiconductor memory device is provided to prevent damage to a conductive layer for the storage electrode and underlying layers together with using a typical wet etch process. CONSTITUTION: An interlayer dielectric(30) is formed on a semiconductor substrate having an access transistor, and a vertical hole is formed in the interlayer dielectric(30) to reach the access transistor. After a polysilicon pattern(32) is formed on the interlayer dielectric(30) and in the vertical hole, a tungsten pattern(34) is formed on the polysilicon pattern(32) to have a width smaller than that of the polysilicon pattern(32). A sidewall spacer(36) is next formed around the tungsten pattern(34), and the polysilicon pattern(32) is etched by using both the sidewall spacer(36) and the tungsten pattern(34) as an etch mask. The tungsten pattern(34) is then removed, and the centrally exposed polysilicon pattern(32) is etched to a predetermined depth. Finally, the sidewall spacer(36) is removed.

Abstract: PURPOSE: A communication method for server system based on asymmetric 3 way TCP is provided to perform communication among a client, a front server and a backend server in order to improve a processing speed by handling data in many back servers. CONSTITUTION: As a request of numbers of client is increased, an acknowledgement number processing part of TCP layer of a server based on internet is modified without modifying a client program in order to perform communication based on an Asymmetric 3 way TCP among a client, a front server and a backend server. Next, many backend servers are installed. When the client served by the backend server sends an acknowledgement TCP segment to a front server, then the acknowledgement TCP segment is properly modified to be processed in a TCP layer of the front server even if the acknowledgement number from the backend server is larger than a number that was expected to be received by the front server. Thus, a command that makes backend servers to process the request of client received by the front server taking the place of the front server, a proper acknowledgement number and a sequence number that the TCP layer of client wants to receive are notified to the backend server. Therefore, a data is processed in the many backend servers as if the data is processed in the front server.

Abstract: PURPOSE: A probe of a voltage tester is provided to prevent an accident from occurring because of the exposed probe while detecting voltage through improving the probe. CONSTITUTION: Of a probe of a voltage tester, if a force is not imposed on a probe(60), the state between the probe(60) and a stopper(54) remains electrically open by the force of a return spring(62). So, except for the testing period, power is not given outside the insulation body(52) maintaining an electrically safe state. If a force is imposed on the probe(60) during the testing, the return spring(62) is compressed retracting the probe(60) contacting the stopper(54) electrically and the stopper(54) is supported elastically by a supporting spring(56). Thus, as power is delivered from the probe(60) to a voltage tester(50), voltage testing is possible. And after the force is released, the probe(60) returns to the original position by elastic restitution of the return spring(62) and the probe(60) and the stopper(54) becomes open again.
