Silicon film grown on sapphire (SOS), useful for device is fabrication, is ordinarily grown at high temperatures approx. 1100 degrees C, using the chemical vapor deposition (CVD) technique. Such a high temperature growth is known to create an appreciable stress in the silicon (Si) film due to the large thermal expansion gradient between the film and substrate.
