Filed: 2001-06-26
Abstract: PURPOSE: A method for fabricating an isolation layer of a semiconductor device is provided to improve reliability and yield and to stabilize a process for forming a shallow trench isolation(STI) layer by preventing the etch loss of an isolation layer. CONSTITUTION: A trench is formed in a semiconductor substrate(21) by using a pad nitride layer and a pad oxide layer(22) whose field region is open to the semiconductor substrate. An oxide layer(25) is formed along the surface of the trench. An undoped polysilicon layer(26) and a high density plasma(HDP) oxide layer(27) are sequentially formed on the resultant structure including the oxide layer to fill the trench. The oxide layer, the undoped polysilicon layer and the HDP oxide layer are left in the trench. The exposed portion of the undoped polysilicon layer is eliminated by a predetermined thickness. The pad nitride layer is removed and a part of the HDP oxide layer protrudes. A nitride layer spacer(28a) is formed on the protruding sidewall of the HDP oxide layer. A thin nitride layer(29) is formed on the nitride layer spacer and the HDP oxide layer.

Abstract: PURPOSE: A method for setting a layer on electronic map based on a web and a recording media in which a program capable of executing the method is recorded is provided to efficiently manage data by outputting various layers included in constructing an electronic map according to a user's request, and by automatically compressing and releasing layer set-up information. CONSTITUTION: A client program checks a reduced scale of a map. In addition, the client program checks whether there's layer set-up information in a cookie of a user PC(ST-1). In case that there's the information, a code is extracted(ST-2). In case that there's no cookie information, a code value of the layer set-up information previously determined is applied(ST-3). The hexadecimal code obtained is converted into a binary code(ST-4). A layer set-up window is generated(ST-5). A user inquires the layer set-up information of the map and changes each symbol of layers and an output state of a label through a symbol selection interface unit and a label selection interface unit(ST-6). It is judged whether a command signal capable of searching maps with layer set-up items changed through a label whole selection/release interface unit is approved(ST-7). A binary code of the information is generated(ST-8). The binary code is converted into a hexadecimal code(ST-9). The hexadecimal code is stored in the cookie of the user PC(ST-10). Simultaneously, the code is transmitted to a server with another map searching key(ST-11). A result of the map searching is received(ST-12). The map is outputted to the map searching window(ST-13).
