Abstract

A method, and the resulting structure, of forming two fins with different types of strain and material on the same substrate.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A semiconductor structure comprising:
 a first fin located on a substrate, wherein the first fin comprises a first strained semiconductor material; and   a second fin located on the substrate, wherein the second fin comprises a second strained semiconductor material.   
     
     
         2 . The structure of  claim 1 , wherein the first strained semiconductor material is strained silicon. 
     
     
         3 . The structure of  claim 1 , wherein the second strained semiconductor material is strained silicon germanium. 
     
     
         4 . The structure of  claim 1 , wherein the first strained semiconductor material has a tensile strain. 
     
     
         5 . The structure of  claim 1 , wherein the second strained semiconductor material has a compressive strain. 
     
     
         6 . The structure of  claim 1 , wherein the substrate is a semiconductor-on-insulator substrate.
