Abstract:
A semiconductor structure includes a substrate, and first isolation structures, at least one buried word line and at least one second isolation structure which are disposed in the substrate. The buried word line intersects the first isolation structures. The second isolation structure intersects the first isolation structures. A material of at least a portion of the second isolation structure is different from a material of the first isolation structures.

Claim (Index 15):
The manufacturing method of the semiconductor structure according to  claim 10 , wherein a method for forming the at least one buried word line comprises:\n forming a second patterned hard mask layer on the substrate; partially removing the substrate using the second patterned hard mask layer as a mask, and forming at least one second opening in the substrate; forming a gate dielectric layer on a portion of a surface of the at least one second opening; and forming the at least one buried word line in the at least one second opening.
