摘要:
A fin field effect transistor (FinFET) and a method of forming the same are introduced. In an embodiment, trenches are formed in a substrate, wherein a region between adjacent trenches defines a fin. A dielectric material is formed in the trenches. A part of the substrate is doped and a region of high dopant concentration and a region of low dopant concentration are formed. Gate stacks are formed, portions of the fins are removed and source/drain regions are epitaxially grown in the regions of high/low dopant concentration. Contacts are formed to provide electrical contacts to source/gate/drain regions.
