    Abstract: One method includes forming a mandrel element above a hard mask layer, forming first and second spacers on the mandrel element, removing the mandrel element, a first opening being defined between the first and second spacers and exposing a portion of the hard mask layer and having a longitudinal axis extending in a first direction, forming a block mask covering a middle portion of the first opening, the block mask having a longitudinal axis extending in a second direction different than the first direction, etching the hard mask layer in the presence of the block mask and the first and second spacers to define aligned first and second line segment openings in the hard mask layer extending in the first direction, etching recesses in a dielectric layer disposed beneath the hard mask layer based on the first and second line segment openings, and filling the recesses with a conductive material.

    Abstract: Methods for processes to form and use merged spacers in fin generation and the resulting devices are disclosed. Embodiments include providing first and second mandrels separated from each other across adjacent cells on a Si layer; forming first and second dummy-spacers and third and fourth dummy-spacers on opposite sides of the first and second mandrels, respectively; removing, through a block-mask, the first and fourth dummy spacers and a portion of the second and third dummy-spacers; forming first spacers on each exposed side of the mandrels and in between the second and third dummy-spacers, forming a merged spacer; removing the mandrels; removing a section of the merged-spacer; forming second spacers on all exposed sides of the first spacers and the merged-spacer; removing the merged-spacer and the first spacers; removing exposed sections of the Si layer through the second spacers; and removing the second spacers to reveal Si fins.
