Methods of forming different FinFET devices with different threshold voltages and integrated circuit products containing such devices

Abstract:

One illustrative method disclosed herein involves forming a first fin for a first FinFET device in and above a semiconducting substrate, wherein the first fin is comprised of a first semiconductor material that is different from the material of the semiconducting substrate and, after forming the first fin, forming a second fin for a second FinFET device that is formed in and above the semiconducting substrate, wherein the second fin is comprised of a second semiconductor material that is different from the material of the semiconducting substrate and different from the first semiconductor material.

Abstract(Chinese):

本文公开的一种说明性方法包括在半导体衬底中和上方形成用于第一FinFET器件的第一鳍片，其中第一鳍片由不同于半导体衬底的材料的第一半导体材料组成，并且在形成第一鳍片之后形成在所述半导体衬底中以及所述半导体衬底上形成的第二FinFET器件的第二鳍片，其中所述第二鳍片由不同于所述半导体衬底的材料并且不同于所述第一半导体材料的第二半导体材料构成。
