An FET device structure has a Fin-FET device with a fin of a Si based material. An oxide element is abutting the fin and exerts pressure onto the fin. The Fin-FET device channel is compressively stressed due to the pressure on the fin. A further FET device structure has Fin-FET devices in a row. An oxide element extending perpendicularly to the row of fins is abutting the fins and exerts pressure onto the fins. Device channels of the Fin-FET devices are compressively stressed due to the pressure on the fins.
