Abstract: A method for vapor deposition includes monitoring of growth of a semiconductor layer by way of in-situ monitoring. According to the invention, in-situ monitoring is performed by irradiating a light beam onto the surface of the growing layer in a direction nearly perpendicular to the surface. Growth parameters of the layer are detected by monitoring variation of the light reflected by the surface of the layer. A growth condition in a vapor deposition chamber is feedback controlled based on the detected growth parameter.
