IPC: H01L29/778
Filed: 1989-06-02
Abstract: PURPOSE:To effectively eliminate an abnormality of an output current-voltage characteristic by a method wherein the impurity concentration of a buffer layer is set, in an operation state, to a concentration by which an impact ionization phenomenon is not caused inside a depletion layer generated near a junction face between the buffer layer and a channel layer. CONSTITUTION:A laminated structure having the following is provided: a buffer layer 13b; a channel layer 14; and an electron supply layer 16 doped with n-type impurities. An impurity concentration of the buffer layer 13b is set, in an opera tion state of a modulation doping heterojunction field-effect transistor, to a concentration by which an impact ionization phenomenon is not caused in a depletion layer generated near a junction face between the buffer layer 13b and the channel layer 14. The superlattice buffer layer 13b easily takes in resid ual impurities inside a chamber, e.g. carbon C, when an AlGaAs layer as one of its constituent layers is grown; consequently, the layer is of a P-type even though it is not doped. Thereby, the output current-voltage characteristic does not display an abnormality and is stabilized in a wide range.
