发明名称 Semiconductor device and method for forming using the same
摘要 A semiconductor device and a method for forming the same are disclosed. The semiconductor device includes a plurality of bit lines having a uniform width on a semiconductor substrate, an active region obliquely arranged to have a predetermined angle with respect to the bit lines, a spacer arranged around the bit lines connected to a center part of the active region. A contact pad is connected to a lower part of the bit lines. The spacer is formed not only at an upper part of sidewalls of the contact pad but also at sidewalls of the bit lines. As a result, a CD of the bit line contact increases, so that a bit line contact patterning margin also increases. A bit line pattern having a uniform width is formed so that a patterning margin increases. A storage electrode contact self-alignment margin increases so that a line-type storage electrode contact margin increases.
