Abstract:
A memory device includes a semiconductor substrate having at least one active area that is defined by a device isolation structure. The memory device further includes two neighboring buried word lines disposed in the semiconductor substrate of the active area. The memory device further includes a trench isolation structure disposed in the semiconductor substrate between the buried word lines.

Claim (Index 11):
A method for manufacturing a memory device, comprising:\n forming a first masking pattern layer on a semiconductor substrate, wherein the semiconductor substrate has at least one active area that is defined by a device isolation structure; etching the semiconductor substrate using the first masking pattern layer as an etch mask, so as to form two neighboring first trenches in the semiconductor substrate of the active area; forming two neighboring buried word lines in the neighboring first trenches; forming an insulating cap layer on the first masking pattern layer, wherein the insulating cap layer fills the neighboring first trenches and on the neighboring buried word lines; patterning the insulating cap layer, the first masking pattern layer, and the semiconductor substrate, so as to form a second trench in the semiconductor substrate between the neighboring buried word lines and a third trench in the insulating cap layer above the second trench, wherein a width of the third trench is greater than a width of the second trench; and filling the second trench with an insulating material, so as to form a trench isolation structure.
