    摘要: A semiconductor memory device (20) includes N bitlines (31, 32, 33, 34) addressable by a partially decoded column address, wherein N is greater two. A column address selection lead (YSEL) has plural segments, each of which overlays a length of one of the bitlines. Each segment of the column address selection lead overlays no more than approximately 1/N of the length of a bitline. Adjacent column address selection leads are separated by approximately the pitch of N-1 bitlines.

    摘要: A multilevel metal and via structure is described. The metal conductors include a base or seed layer, a bulk conductor layer, a capping layer, and a barrier layer, and the via structure include a seed layer, a diffusion barrier layer and a metal plug.The via seed layer is controlled to a thickness that discourages the reaction between the via seed layer and the bulk conductor layer. The reaction may result in the formation of harmful voids at the bottom of the vias and is caused by having the via seed metal coming in contact with the bulk conductor through openings in the barrier layer.
