Abstract:
A method of forming a semiconductor device. The method may include providing a device structure, where the device structure comprises a masked portion and a cut portion. The masked portion may comprise a mask covering at least one semiconductor fin of a fin array, and the cut portion may comprise a trench, where the trench exposes a semiconductor fin region of the fin array. The method may further include providing an exposure of the trench to oxidizing ions, the oxidizing ions to transform a semiconductor material into an oxide.

Claim (Index 16):
A method for forming a finFET device, comprising\n providing a fin array on a substrate, the fin array comprising a plurality of tapered semiconductor fins, wherein the tapered semiconductor fins are separated by an isolation oxide; forming a mask on the fin array, the mask defining a fin cut region; etching the fin array while the mask is in place to form a trench in the fin array in the fin cut region, wherein the trench extends from a surface of the mask to a bottom of the semiconductor fins; and performing a plasma oxidation of the fin array while the mask is in place, wherein oxidizing ions are implanted into the trench, wherein the oxidizing ions are directed as an ion beam having a shape of a ribbon beam to the substrate, the ion beam defining a trajectory forming a non-zero angle of incidence with respect to a perpendicular to a plane of the substrate.
