Claim 11:
12. A method for forming the dynamic random access memory of claim 1, comprising:
forming the plurality of bit line contact structures on the substrate;
forming the plurality of bit line structures on the bit line contact structures, wherein each of the bit line structures extends along the first direction;
forming the plurality of first insulating structures on the substrate, wherein each of the first insulating structures extends in the second direction crossing the first direction;
forming the capacitor contact structure on the substrate, wherein the capacitor contact structure is between adjacent ones of bit line structures and adjacent ones of first insulating structures;
forming the first connecting pad on the capacitor contact structure;
forming the second insulating structure surrounding the first connecting pad, wherein the top width of the second insulating structure is greater than the bottom width of the second insulating structure; and
forming the capacitor structure on the first connecting pad and electrically connecting the first connecting pad.
