Claim Text:
1. A finFET device having fins formed of at least two different materials, comprising: a substrate with a first layer; a first oxide layer with a top surface opposite the first layer, the first oxide layer located on the first layer and configured to cover a first portion of the first layer and not a second portion of the first layer; a first body of material at the second portion of the first layer, the first body of material includes a top surface even with the top surface of the first oxide layer; a first set of fins formed of a first material on the first oxide layer, the first set of fins configured to form a first channel for a first charge carrier; and a second set of fins formed of a second material on the first body of material layer, the second set of fins configured to form a second channel for a second charge carrier.
