发明名称 METHOD FOR FABRICATING FINE PATTERN IN SEMICONDUCTOR DEVICE
摘要 A method for fabricating a pattern in a semiconductor device includes a single polysilicon hard mask by appropriately selecting spacer material in an SPT, thereby decreasing the number of fabrication processes. Furthermore, since the spacers are easily removed, it is possible to prevent the formation of a step between patterns of a cell region and a peripheral region.
