Abstract: Various embodiments include methods and integrated circuit structures. In some cases, an integrated circuit (IC) structure includes: a substrate; a set of fin structures overlying the substrate, the set of fin structures including a substrate base and a silicide layer over the substrate base; an oxide layer located between adjacent fins in the set of fin structures; and a nitride layer over the set of fin structures, wherein a height of the nitride layer is substantially uniform across the set of fin structures.

Abstract: Various embodiments include methods and integrated circuit structures. In some cases, a method of forming an integrated circuit structure can include: forming a mask over an oxide layer and an underlying set of fin structures, the set of fin structures including a plurality of fins each having a substrate base and a silicide layer over the substrate base; implanting the oxide layer through an opening in the mask; removing the mask; polishing the oxide layer overlying the set of fin structures after removing the mask to expose the set of fin structures; and forming a nitride layer over the set of fin structures.
