Abstract
A semiconductor device, comprising a nitride semiconductor layer, a switching element, and a driving transistor; the switching element comprises: a first portion of a first electrode formed on the nitride semiconductor layer; a second electrode formed on the nitride semiconductor layer; and a first control electrode formed on the nitride semiconductor layer and located between the first portion of the first electrode and the second electrode; the driving transistor comprises: a second portion of the first electrode formed on the nitride semiconductor layer and connecting the first portions of the adjacent first electrodes to each other; a third electrode formed on the nitride semiconductor layer and transmitting a signal to the first control electrode; and a second control electrode formed on the nitride semiconductor layer and located between the second portion of the first electrode and the third electrode. Therefore, when the switching element is turned off, it can be kept in an off state even if a drain voltage applied to the switching element is subjected to a variation or the like.
