Abstract
Transistors include stress liners, with one or more semiconductor structures between the stress liners. The stress liners provide a stress on the one or more semiconductor structures. A gate is formed over and around the one or more semiconductor structures. A source and drain region is formed on the one or more semiconductor structures on opposite sides of the gate, between the stress liners.
