    摘要: A semiconductor product includes, a substrate with a first dielectric layer having contact hole fillings for contacting active areas in the substrate. A second dielectric layer with contact holes is provided therein. The contact holes have a width in a first lateral direction. The product further includes conductive lines, each conductive line passing over contact holes in the second dielectric layer and contacting a plurality of contact hole fillings in the first dielectric layer. The conductive lines have a width, in the first lateral direction, that is smaller than the width of the contact holes of the second dielectric layer. The conductive lines are in direct mechanical contact with the contact hole fillings and thereby remove the need to provide any conventional “contact to interconnect” structures.

    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: A method of forming a contact between a bitline and a local interconnect in a flash memory device comprises forming a hard mask layer on a planarized surface that includes an exposed top section of the local interconnects prior to depositing an oxide dielectric layer. The hard mask layer may be composed of a material that has an etch resistance as compared to the interlayer dielectric material, e.g., nitride. Openings in the hard mask define positions for the contacts to the local interconnects exposed in the top section.
