METHOD OF FORMING SEMICONDUCTOR DEVICE USING EMBEDDED L-SHAPED SPACER, AND SEMICONDUCTOR DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device in which an L-shaped spacer is embedded. SOLUTION: The method includes a step of defining an L-shaped spacer on each side of a gate region of a substrate; and a step of embedding the L-shaped spacer in an oxide layer so that the oxide layer covers a portion of the substrate to a predetermined distance from a side edge of the L-shaped spacer. Further, an oxide layer is removed to expose the L-shaped spacer. COPYRIGHT: (C)2007,JPO&INPIT
