Abstract
A semiconductor structure comprising a first transistor element and a second transistor element is provided. Stress in channel regions of the first and the second transistor element is controlled by forming stressed layers having a predetermined stress over the transistors. The stressed layers may be used as etch stop layers in the formation of contact vias through an interlayer dielectric formed over the transistors.
