摘要: 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.

摘要: Embodiments of present invention provide a method of forming a first and a second group of fins on a substrate; covering a top first portion of the first and second groups of fins with a first dielectric material; covering a bottom second portion of the first and second groups of fins with a second dielectric material, the bottom second portion of the first group and the second group of fins having a same height; exposing a middle third portion of the first and second groups of fins to an oxidizing environment to create an oxide section that separates the top first portion from the bottom second portion of the first and second groups of fins; and forming one or more fin-type field-effect-transistors (FinFETs) using the top first portion of the first and second groups of fins as fins under gates of the one or more FinFETs.
