Abstract:
A semiconductor memory device includes a cell array region formed on a substrate, a word line contact region, and a page buffer region coupled to the cell array region through bit lines, wherein at least one of the bit lines has a curved structure toward the word line contact region. According to an embodiment, a misalignment between a cell plug and a contact plug caused by a natural cell plug bending phenomenon may be reduced to improve operational reliability of a semiconductor memory device.

Claim (Index 15):
A method of manufacturing a semiconductor memory device comprising:\n forming a stacked structure on a substrate, wherein the stacked structure includes word lines stacked on a cell array region a substrate and cell plugs, wherein the substrate includes the cell array region, a word line contact region and a page buffer region; forming first contact plugs coupled to the cell plugs in the cell array region; forming second contact plugs coupled to transistors in the page buffer region; and forming bit lines coupling the first contact plugs and the second plugs so that the page buffer region is coupled to the cell array region through the bit lines, wherein one of the first contact plugs is shifted to the word line contact region with respect to a corresponding second contact plug and a distance by which the one of the first contact plugs is shifted with respect to the corresponding second contact plug is greater than a distance by which another first contact plug is shifted with respect to a corresponding second contact plug.
