PURPOSE:To enable a capacity portion to be constructed on a bit line and also positioning margin between the bit line and a bit line contact to be increased. CONSTITUTION:Element regions 1 are alternately aligned, a bit line 3 is placed between these and then one bit line 3 is allowed to contact the element regions 1 at both sides. Since a portion which does not overlap the bit line 3 is produced at the element region 1, a capacity portion can be constructed on the bit lines, thus enabling a positioning margin of the bit line contact to be increased. Also, when both the element regions and the bit lines are skewly merged for a word line, the same effect as above can be obtained since a portion where the element regions do not overlap the bit lines is produced. |
