Notes:
We report on the uniformity of composition and thickness of epitaxial GexSi1−x layers grown by ultrahigh vacuum chemical-vapor deposition. Double-crystal x-ray diffractometry showed that variations in thickness are less than ±2.2% and variations in composition less than ±2.5% from center to edge of a 75 mm wafer. The variations observed are consistent with the predictions of Monte Carlo simulations.
