    摘要: A semiconductor product (1) includes a plurality of wordlines extending along a first lateral direction (x) along a substrate surface (22) and also includes contact structures (3) as well as filling structures (4) therebetween. Along the first direction (x) the contact structures (3) and the filling structures (4) are arranged in alternating order between two respective wordlines. Each contact structure (3) serves to connect two active areas (23) separated by one respective trench isolation filling (24) to a respective bitline (14). Accordingly, the width of the first contact structures (3) is much larger than the width of the bitlines (14) along the first direction (x). According to embodiments of the invention, tapered upper portions (9) of the contact structures (3) are shaped, the upper portions (9) having a width being significantly smaller than the width of the contact structures (3) along the first direction (x). Thereby, forming the bitlines (14) in direct contact to top surfaces (7) of contact structures (3) is possible without the risk of short circuits between adjacent bitlines (14).

    摘要: Dielectric gratings are formed between the word line stacks. Spacers are applied to the sidewalls of the word line stacks and the dielectric gratings. In the openings between the spacers, silicon is epitaxially grown on the upper surfaces of source/drain regions, which are implanted self-aligned to the word line stacks. A silicide is formed on the grown silicon, and a metal layer is applied and structured to form local interconnects, which connect the source/drain regions to upper bit lines.

    摘要: A semiconductor structure includes first and second conductive lines which cross each other. The second conductive lines are electrically insulated from the first conductive lines via an insulating material. The second conductive lines include first and second sections. First sections are arranged beneath crossing first conductive lines and include a semiconductor material. The second sections are disposed between adjacent first conductive lines and include a metal-semiconductor compound. A method of manufacturing a semiconductor structure involves forming initial second conductive lines, forming first conductive lines and providing a metal-semiconductor compound on an exposed surface of the initial second conductive lines, thereby obtaining second conductive lines. Forming the metal-semiconductor compound is performed after forming the first conductive lines.
