Abstract:
A method of fabricating a semiconductor memory device includes forming a bit line and a bit line capping pattern on the semiconductor substrate, forming a first spacer covering a sidewall of the bit line capping pattern and a sidewall of the bit line, forming a contact plug in contact with a sidewall of the first spacer and having a top surface that is lower than an upper end of the first spacer, removing an upper portion of the first spacer, forming a first sacrificial layer closing at least an entrance of the void, forming a second spacer covering the sidewall of the bit line capping pattern and having a bottom surface in contact with a top surface of the first spacer, and removing the first sacrificial layer. The bit line capping pattern is on the bit line. The contact plug includes a void exposed on the top surface.

Claim (Index 15):
The method of  claim 13 , wherein\n the forming the protective layer includes forming the protective layer to extend and cover an entire surface of the semiconductor substrate, and the protective layer includes one of a polysilicon layer, a silicon oxide layer, or a silicon nitride layer including boron, and the performing the cleaning process includes completely removing the protective layer.
