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 2):
The method of  claim 1 , wherein\n the forming the first sacrificial layer includes forming the first sacrificial layer as an oxide layer, and the forming the first sacrificial layer includes,\n coating an entire surface of the semiconductor substrate with a solution including oxygen, and \n baking the solution.
