Abstract: An apparatus includes: a plurality of capacitors each including first and second conductive portions and a dielectric portion therebetween; a first conductive structure containing the plurality of capacitors therein, and electrically coupled to the second conductive portions of the plurality of capacitors; a second conductive structure on a top surface of the first conductive structure; and a third conductive structure on a top surface of the second conductive structure.

Abstract: An apparatus includes: a first memory mat; a second memory mat adjacent to the first memory mat; a peripheral circuit between the first memory mat and the second memory mat, the peripheral circuit defining a first boundary to the first memory mat and a second boundary to the second memory mat and including a plurality of wiring patterns in a wiring layer; and at least one dummy pattern in the wiring layer arranged on or along the first boundary.

Abstract: A semiconductor device includes a substrate, a memory cell region, a peripheral region adjacent to the memory cell region, a plurality of word-lines extending across the memory cell region and the peripheral region, and a plurality of contacts connected to edge portions of even numbered ones of the plurality of word-lines in the peripheral region, respectively.

Abstract: A semiconductor device includes: a substrate; a memory cell region provided over the substrate; a peripheral region provided over the substrate and adjacent to the memory cell region; a plurality of word-lines extending across the memory cell region and the peripheral region; and a plurality of contacts connected to edge portions of even numbered ones of the plurality of word-lines in the peripheral region, respectively; wherein a side of each of the edge portions of the even numbered ones of the plurality of word-lines is adjacent a portion missing an odd numbered word-line; and wherein another side of each of the edge portions of the even numbered ones of the plurality of word-lines is adjacent an offcut of another odd numbered word-line.
