A semiconductor FinFET device includes a plurality of gate lines formed in a first direction, and two types of fin structures. A first type of fin structures is formed in a second direction, and a second type of fin structures formed perpendicular to the first type of fin structures. A contact hole couples to one or more of the second type of fin structures.

A method for generating a layout for a device having FinFETs from a first layout for a device having planar transistors is disclosed. A plurality of elongate mandrels is defined in a plurality of active regions. Where adjacent active regions are partially-parallel and within a specified minimum spacing, connective elements are added to a portion of the space between the adjacent active regions to connect the mandrel ends from one active region to another active region.

A method includes growing a plurality of parallel mandrels on a surface of a semiconductor substrate, each mandrel having at least two laterally opposite sidewalls and a predetermined width. The method further includes forming a first type of spacers on the sidewalls of the mandrels, wherein the first type of spacers between two adjacent mandrels are separated by a gap. The predetermined mandrel width is adjusted to close the gap between the adjacent first type of spacers to form a second type of spacers. The mandrels are removed to form a first type of fins from the first type of spacers, and to form a second type of fins from spacers between two adjacent mandrels. The second type of fins are wider than the first type of fins.

A method for forming a plurality of fins on a semiconductor substrate includes depositing a spacer layer to fill in gaps between the plurality of fins, the fins comprising a first material and the spacer layer comprising a second material. A first area is defined where the fins need to be broadened and a second area is defined where the fins do not need to be broadened. The method also includes patterning the spacer layer to remove spacers in the first area where the fins need to be broadened and applying an epitaxy process at a predetermined rate to grow a layer of the first material on fins in the first area. The spacer layer is removed in the second area where the fins do not need broadening.

A bipolar junction transistor (BJT) formed using a fin field-effect transistor (FinFET) complimentary metal-oxide-semiconductor (CMOS) process flow is provided. The BJT includes an emitter fin, a base fin, and a collector fin formed on a substrate. The base fin encloses the emitter fin and collector fin encloses the emitter fin. In some embodiments, the emitter fin, base fin, and collector fin have a square shape when viewed from above and are concentric with each other.
