发明名称 SEMICONDUCTOR DEVICE HAVING A REDUCED BIT LINE PARASITIC CAPACITANCE AND METHOD FOR MANUFACTURING THE SAME
摘要 A semiconductor device having a reduced bit line parasitic capacitance and a method of making same is presented. The semiconductor device includes a first, second, third, and fourth interlayer dielectric layers, first and second bit lines, first and second landing plug and first and second storage node contacts. An optional capacitor may be added to complete a CMOS configuration for the semiconductor device. The storage node contacts traverse through the interlayer dielectric layer and are electrically coupled to their respective landing plug contacts. The storage node contacts are deliberately offset, relative to the center of the corresponding landing plug contacts, at a predetermined distance in a direction away from the first bit line. This offsetting aids reducing the parasitic capacitance between the bit line and a storage node.
