Abstract
An efficient strain-inducing mechanism may be provided on the basis of a piezoelectric material so that performance of different transistor types may be enhanced by applying a single concept. For example, a piezoelectric material may be provided below the active region of different transistor types and may be appropriately connected to a voltage source so as to obtain a desired type of strain.
