| 摘要 |
The present invention relates to semiconductor memory device junction and a method of forming the same. The semiconductor memory device junction may include a semiconductor substrate having gate lines formed thereon, and a junction having first and second junction elements formed by implanting impurities of a different mass into the semiconductor substrate between the gate lines. The method of forming a semiconductor memory device junction may include providing a semiconductor substrate having gate lines, forming an auxiliary layer along a surface of the semiconductor substrate including the gate lines, implanting impurities into the semiconductor substrate between gate lines to form a first junction element, and implanting impurities into the semiconductor substrate to form a second junction element, wherein the impurities implanted to form the first junction element and the second junction element have different masses.
