Abstract:
A method of forming fins of different materials includes providing a substrate with a layer of a first material having a top surface, masking a first portion of the substrate leaving a second portion of the substrate exposed, etching a first opening at the second portion, forming a body of a second material in the opening to a level of the top surface of the layer of the first material, removing the mask, and forming fins of the first material at the first portion and forming fins of the second material at the second portion. A finFET device having fins formed of at least two different materials is also disclosed.
