Claim Text:
1. A semiconductor structure, comprising: a substrate having a trench; a stacked strip structure formed in the trench, comprising: a plurality of conductive strips, wherein each of the conductive strips has a horizontal conductive segment and two vertical conductive segments connected to the corresponding horizontal conductive segment, the horizontal conductive segments extend in a direction parallel to a bottom of the trench, and the vertical conductive segments extend in a direction perpendicular to the bottom of the trench; and a plurality of insulating strips, wherein the conductive strips and the insulating strips are interlaced, each of the insulating strips has a horizontal insulating segment and two vertical insulating segments connected to the corresponding horizontal insulating segment, and the vertical insulating segments extend in a direction parallel to the direction in which the vertical conductive segments extend; and at least one conductive structure electrically connected to at least one of the conductive strips; wherein the stacked strip structure has a horizontal stacked portion corresponding to the horizontal conductive segments and two vertical stacked portions corresponding to the vertical conductive segments, and a width of the vertical stacked portions is larger than a thickness of the horizontal stacked portion, and wherein a width of the vertical insulating segments is larger than a thickness of the corresponding horizontal insulating segment.
