CHANNEL SiGe DEVICES WITH MULTIPLE THRESHOLD VOLTAGES ON HYBRID ORIENTED SUBSTRATES, AND METHODS OF MANUFACTURING SAME

Abstract

Multiple threshold voltage devices on hybrid oriented substrates, and methods of manufacturing same are disclosed. A method for manufacturing a semiconductor device comprises performing a single epitaxy step on a hybrid orientation substrate including a first region having a first crystallographic orientation and a second region having a second crystallographic orientation different from the first crystallographic orientation, wherein the single epitaxy step forms a first layer disposed on the first region and a second layer disposed on the second region, the first layer has the first crystallographic orientation and a first composition, and the second layer has the second crystal orientation and a second composition different from the first composition.
