Abstract:
A method for fabricating a semiconductor device includes: forming a first conductive layer; forming a second conductive layer over the first conductive layer; forming a conductive line by etching the second conductive layer; etching a portion of the first conductive layer to form a plug head having the same critical dimension as the conductive line; forming a first spacer that covers the conductive line and the plug head; etching the remaining first conductive layer to form a plug body that is aligned with the first spacer, wherein the plug body have a greater critical dimension than the plug head; and forming a second spacer by performing a selective oxidation onto a side wall of the plug body.

Claim (Index 18):
The method of  claim 8 , further comprising:\n forming a storage node contact plug to be adjacent to the plug body, the plug head, and the bit line, after the forming of the third spacer that covers the first spacer and the second spacer and fills the gap; and forming a capacitor over the storage node contact plug.
