摘要： A field-effect transistor includes a semi-insulating substrate, a semiconductor layer consisting of successive layers of GaAs compound semiconductor formed on the substrate, a gate electrode forming a Schottky contact with the semiconductor layer, and source and drain electrodes each forming an ohmic contact to the semiconductor layer. A semiconductor layer includes a buffer layer, an active layer, and a contact layer, where the impurity concentration in the contact layer is substantially equal to that in the active layer at the interface therewith. The impurity concentration in the contact layer increases continuously from the interface toward the upper surface of the contact layer. The field-effect transistor achieves a reduction in the ON resistance and an increase in the gate breakdown voltage at the same time, and to reduce power loss and increase efficiency.

摘要： An electronic component is mounted on a substrate so as to be in contact with a non-reciprocal circuit element. Therefore, there is no risk of the electronic component, which is arranged so as to be in contact with the non-reciprocal circuit element, being displaced as a result of being shifted by the magnetic force of permanent magnets included in the non-reciprocal circuit element and displacement of the electronic component as a result of being shifted by the magnetic force of the permanent magnets can be prevented. Therefore, since there is no risk of the electronic component being displaced by being shifted by the magnetic force of the permanent magnets, a space in which to mount a member that would function as an electromagnetic shield, such as a yoke, need not be provided on the substrate and the composite electronic module can be reduced in size and profile.
