Abstract: PURPOSE: A method for fabricating a contact and a bitline of a flash memory device is provided to simplify a fabricating process and to reduce fabricating cost, by preventing a contact plug electrically connecting the bitline with a drain from causing a bridge between adjacent bitlines. CONSTITUTION: The first interlayer dielectric(110) is formed on a semiconductor substrate(100). An etch stop layer(116) is formed on the first interlayer dielectric. The second interlayer dielectric(114) is formed on the etch stop layer. The first photoresist pattern defining a bitline region is formed on the second interlayer dielectric by a photolithography process. The second interlayer dielectric is etched by using the first photoresist pattern as a mask. The etch stop layer is etched by using the first photoresist pattern as a mask. The first photoresist pattern is eliminated. A contact hole for connecting the bitline with a source and a contact hole for connecting the bitline with a peripheral circuit region are formed in a predetermined portion of a bitline formation region on the first interlayer dielectric. A barrier layer is deposited on the semiconductor substrate. A conductive layer is so deposited on the semiconductor substrate to form the bitline while completely filling the contact holes. The conductive layer is planarized by a chemical mechanical polishing(CMP) process.

Abstract: PURPOSE: A method for discriminating and displaying an abnormal URL on the Internet is provided to detect an abnormal URL linked in an HTML document to be supplied to a user by a web browser or a web server using an HTTP protocol in the case that an Internet service is supplied. CONSTITUTION: If a user requests a predetermined document 'A' to a web server while the user receives an Internet service using a web browser embodied in one's PC, the web browser requests an URL of the document 'A' to the first web server(S31). Thus, the user receives the document 'A' as an HTML format(S32). The web browser analyzes an HTML tag or other script tag of the received document 'A', detects all URLs linked in the document 'A', transmits a request message to the second web server corresponded to each URL in accordance with an HTTP protocol, and tries an access(S33). The web browser discriminates whether each URL is a service available normal URL. The web browser transmits a request message to the second web server corresponded to each URL, and sets a timer for checking whether a response message is reached within a predetermined time(S34). In the case that a response message is reached within a predetermined time, the web browser checks whether the reached response message is set by a state code which displays an error state(S35). If the reached response message is set by a state code which displays an error state, the corresponding URL in the document 'A' to be supplied to the user is displayed as abnormal URL and supplied(S36,S38).
