Abstract: PURPOSE:To eliminate the increase in gate leakage current or deterioration in gate pressure resistance covering an In-included mesa type chemical compound semiconductor layer's mesa side wall and its surrounding with an amorphous III-group semiconductor layer. CONSTITUTION:A 1mum thick undoped AlInAs buffer layer, a 20 -nm thick Si doped InGaAs operating layer 4, a 20nm thick undoped AlInAs insulation layer 5 are adapted to make an epitaxial growth successively on a semi-insulation InP substrate 1, thereby forming a mesa section which is a device region. The side wall of the mesa section and its surrounding are covered with an amorphous III-V group chemical compound semiconductor layer 3, thereby forming a Ti/Pt/Au-made electrode 6, and AuGe/Ni-made source electrode 7, and drain electrode 8. Since the side wall of the mesa section is covered with the AlInAs insulation film insulation layer or amorphous GaAs insulation layer 3, for example, gate leakage current is minimized so that pressure resistance may be enhanced.

The silicon nitride film 6' is patterned with the resist pattern used as a mask to obtain an upper insulation film 6. In this manner, the manufacturing processes can be remarkably simplified while, at the same time, the yield can be improved.

For the oil pressure in a front chamber 53, its removal is accelerated by the initial duty ratio given, and it is drained speedily. The initial duty ratio is at a value set corresponding to a vehicle speed.
