Abstract: Embodiments of the present invention provide a method of forming semiconductor structure. The method includes forming a set of device features on top of a substrate; forming a first dielectric layer directly on top of the set of device features and on top of the substrate, thereby creating a height profile of the first dielectric layer measured from a top surface of the substrate, the height profile being associated with a pattern of an insulating structure that fully surrounds the set of device features; and forming a second dielectric layer in areas that are defined by the pattern to create the insulating structure. A structure formed by the method is also disclosed.

Abstract: FinFET structures with dielectric fins and methods of fabrication are disclosed. A gas cluster ion beam (GCIB) tool is used to apply an ion beam to exposed fins, which converts the fins from a semiconductor material such as silicon, to a dielectric such as silicon nitride or silicon oxide. Unlike some prior art techniques, where some fins are removed prior to fin merging, in embodiments of the present invention, fins are not removed. Instead, semiconductor (silicon) fins are converted to dielectric (nitride/oxide) fins where it is desirable to have isolation between groups of fins that comprise various finFET devices on an integrated circuit (IC).

Abstract: An improved finFET and method of fabrication using a silicon-on-nothing process flow is disclosed. Nitride spacers protect the fin sides during formation of cavities underneath the fins for the silicon-on-nothing (SON) process. A flowable oxide fills the cavities to form an insulating dielectric layer under the fins.
