Classification: CPC H | IPC H

Claim 11:
12. The semiconductor structure of claim 1, further comprising:
a second bit line on the substrate, wherein the contact is disposed between the first bit line and the second bit line, and the dielectric layer is conformally disposed over the second bit line; and
a second air gap, sealed by the dielectric layer and defined by the second bit line, the substrate and the contact;
wherein the dielectric layer further has a fourth dielectric layer portion formed at a side surface of the second bit line, a fifth dielectric layer portion formed on the top surface of the substrate and positioned apart from the second dielectric layer portion, and a sixth dielectric layer portion formed at an opposed side surface of the contact;
wherein the second air gap is sealed within the fourth through sixth dielectric layer portions of the dielectric layer.
