Filed: 1986-10-20
Abstract: PURPOSE:To reduce a channel layer so made of a graded compound semiconductor as to increase the composition value of In toward a surface to be in contact with an electrode thereby to improve mutual conductance gm by providing the channel layer. CONSTITUTION:A channel layer made of an undoped InxGax-1As channel layer 5A and an undoped InuGa1-uAs graded channel layer 5B is formed of a compound semiconductor so graded that an In composition value is increased toward a surface to be in contact with an electrode. Thus, since a surface depletion layer is not extended thereby to the channel layer, a two-dimensional carrier gas layer 10 is not affected by the adverse influence of a surface depletion layer. Accordingly, a channel layer can be reduced in thickness. Then, the distance between e gate electrode and the gas layer is shortened to enhance mutual conductance gm thereby to decrease power consumption. Further carrier gas concentration in the gas layer can be efficiently controlled.
