Abstract:
A semiconductor device includes a substrate having a trench, a bit line in the trench, a first spacer extending along the trench and at least a portion of a side surface of the bit line and in contact with the bit line, and a second spacer disposed within the trench on the first spacer. The bit line is narrower than the trench, and the first spacer includes silicon oxide. A method of forming a semiconductor device includes forming a trench in a substrate, forming a bit line within the first trench of width less than that of the first trench, and forming a first spacer that lines a portion of the trench and includes silicon oxide in contact with at least a portion of a side surface of the bit line, and forming a second spacer over the first spacer in the trench.

Claim (Index 13):
The semiconductor device of  claim 12 , wherein the first spacer has an inner portion extending along said at least a portion of the side surface of the first bit line and an outer portion lining said part of the first trench, and\n the outer portion of the first spacer is in contact with the buried contact.
