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

    Abstract: A semiconductor device realizing a power transistor capable of operating in a complete enhancement mode and excellent in low-distortion high-efficiency characteristic. Over one side of a substrate (1) of single crystal GaAs, a buffer layer (2), a second barrier layer (3) of AlGaAs, a channel layer (4) of InGaAs, a third barrier layer (12) of InGaP, and a first barrier layer (11) of AlGaAs are formed in this order. The first and third barrier layers (11, 12) satisfy the relation x 1 - x 3 & 0.5*(Eg3 - Eg1) where x 1 is the electron affinity of the first barrier layer (11), Eg1 is the band gap thereof, x 3 is the electron affinity of the third barrier layer (12), and the Eg3 is the band gap thereof.
