Abstract:
A semi-damascene method is described for fabricating wordlines without stringers while maintaining critical cell dimensions when wordline pitch is less than 40 nm. A thin conducting layer protects a storage layer during manufacture, the thin conducting layer then making contact with filled-in conducting material.
Abstract:
A high aspect ratio structure is provided. The high aspect ratio structure includes a substrate, a plurality of stack structures, and a plurality of support structures. The stack structures are disposed on the substrate, and a trench is formed between adjacent two stack structures. Each of the stack structures includes a plurality of first material layers and a plurality of second material layers. The second material layers and the first material layers are disposed alternately. The support structures are respectively disposed between the substrate and the stack structures, wherein each of the support structures has a concave-convex surface.
Abstract:
A semiconductor structure and a manufacturing method of the same are provided. The semiconductor structure includes a substrate, a stacked strip structure, and a tensile material strip. The stacked strip structure is formed vertically on the substrate, the stacked strip structure having compressive stress. The stacked strip structure comprises a plurality of conductive strips and a plurality of insulating strips, and the conductive strips and the insulating strips are interlaced. The tensile material strip is formed on the stacked strip structure, the tensile material strip having tensile stress.
