    摘要: A memory array and a method for preparing the memory are provided. The memory array includes a semiconductor substrate, an isolation structure and contact enhancement sidewall spacers. The semiconductor substrate has a trench defining laterally separate active areas formed of surface regions of the semiconductor substrate. Top surfaces of a first group of the active areas are recessed with respect to top surfaces of a second group of the active areas. The isolation structure is filled in the trench and in lateral contact with bottom portions of the active areas. The contact enhancement sidewall spacers laterally surround top portions of the active areas, respectively.

    摘要: The present application discloses a method for fabricating a semiconductor device with liners. The method includes providing a substrate having a first surface and a second surface opposite to the first surface, inwardly forming a trench on the first surface of the substrate, forming a plurality of liners positioned on side surfaces of the trench, forming a first insulating segment filling the trench, and removing part of the substrate from the second surface to expose the first insulating segment and the plurality of liners.
