Abstract:
Methods of fabricating semiconductor structures involve the formation of fins for finFET transistors having different stress/strain states. Fins of one stress/strain state may be employed to form n-type finFETS, while fins of another stress/strain state may be employed to form p-type finFETs. The fins having different stress/strain states may be fabricated from a common layer of semiconductor material. Semiconductor structures and devices are fabricated using such methods.
