Abstract:
The present disclosure provides a method for preparing a semiconductor memory structure. The method includes the following steps: providing a substrate comprising a plurality of active regions extending in a first direction; forming a plurality of first trenches in the substrate, the first trenches comprising a first depth and extending in a second direction different from the first direction; forming a plurality of buried digit lines in the first trenches; forming a plurality of second trenches in the substrate, the second trenches comprising a second depth and extending in a third direction different from the first direction and the second direction; deepening portions of the second trenches to form a plurality of third trenches in the substrate, the third trenches comprising a third depth; and forming a plurality of buried word lines in the third trenches.

Claim (Index 9):
The method of  claim 8 , further comprising a plurality of capacitors electrically connected to the second doped regions on the substrate.
