An un-programmed e-fuse includes a via of a first conductive material having a bottom and sidewalls with a portion of the sidewalls being covered by a conductive liner and the bottom of the via being formed on top of a dielectric layer, and a first and a second conductive path of a second conductive material formed on top of the dielectric layer with the first and second conductive paths being conductively connected through, and only through, the via at the sidewalls. A programmed e-fuse includes a via; a first conductive path at a first side of the via and being separated from sidewalls of the via by a void; and a second conductive path at a second different side of the via and being in conductive contact with the via through sidewalls of the via.

摘要： A stack of a second photoresist having a second photosensitivity and a first photoresist having a first photosensitivity, which is greater than second photosensitivity, is formed on a substrate. A first pattern is formed in the first photoresist by a first exposure and a first development, while the second photoresist underneath remains intact. A second pattern comprising an array of lines is formed in the second photoresist. An exposed portion of the second photoresist underneath a remaining portion of the first photoresist forms a narrow portion of a line pattern, while an exposed portion of the second photoresist outside the area of the remaining portions of the photoresist forms a wide portion of the line pattern. Each wide portion of the line pattern forms a bulge in the second pattern, which increases overlay tolerance between the second pattern and the pattern of conductive vias.

摘要： A recessed region containing a line portion and a bulge portion is formed in a hard mask layer. Self-assembling block copolymers containing two or more different polymeric block components that are immiscible with one another are applied within the recessed region and annealed. A cylindrical polymeric block centered at the bulge portion is removed selective to a polymeric block matrix surrounding the cylindrical polymeric block. A via cavity is formed by transferring the cavity formed by removal of the cylindrical polymeric block into a dielectric layer. The pattern in the hard mask layer is subsequently transferred into the dielectric layer to form a line cavity. A metal via and a metal line are formed by deposition and planarization of metal. The metal via is self-aligned to the metal line.
