Abstract: Methods pattern a sacrificial material on an etch mask into mandrels using optical mask lithography, form a conformal material and a fill material on the mandrels, and planarize the fill material to the level of the conformal material. Such methods pattern the fill material into first mask features using extreme ultraviolet (EUV) lithography. These methods partially remove the conformal material to leave the conformal material on the sidewalls of the mandrels as second mask features. Spaces between the first mask features and the second mask features define an etching pattern. The spacing distance of the mandrels is larger than the spacing distance of the second mask features. Such methods transfer the etching pattern into the etch mask material, and subsequently transfer the etching pattern into an underlying layer. Openings in the underlying layer are filled with a conductor to form wiring in the etching pattern.

Abstract: The disclosed technology generally relates to semiconductor fabrication, and more particularly to a method of defining routing tracks for a standard cell semiconductor device, and to the standard cell semiconductor device fabricated using the method. In one aspect, a method of defining routing tracks in a target layer over a standard cell semiconductor device includes forming mandrels and forming a first set and a second set of spacers for defining the routing tracks. The standard cell semiconductor device includes a device layer and the routing tracks for contacting a device layer. The routing tracks include at least two pairs of off-center routing tracks, a central routing track arranged between the pairs of off-center routing tracks, and at least two edge tracks arranged on opposing sides of the at least two pairs of off-center routing tracks. A minimum distance between an off-center routing track and the central routing track next to the off-center routing track is smaller than a minimum distance between adjacent off-center routing tracks.

Abstract: Embodiments of the present invention provide a method for cuts of sacrificial metal lines in a back end of line structure. Sacrificial Mx+1 lines are formed above metal Mx lines. A line cut lithography stack is deposited and patterned over the sacrificial Mx+1 lines and a cut cavity is formed. The cut cavity is filled with dielectric material. A selective etch process removes the sacrificial Mx+1 lines, preserving the dielectric that fills in the cut cavity. Precut metal lines are then formed by depositing metal where the sacrificial Mx+1 lines were removed. Thus embodiments of the present invention provide precut metal lines, and do not require metal cutting. By avoiding the need for metal cutting, the risks associated with metal cutting are avoided.
