Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device comprising a compound semiconductor having a good operating characteristic.  <P>SOLUTION: A mesa part formed on a substrate 1 comprises a high resistance layer 2, a channel layer 3 composed of Si-doped GaAs, a high resistance layer 4 composed of undoped GaAs, and a contact layer 5 composed of Si-doped GaAs. At the center of the mesa part, the contact layer 5 is etched and removed to expose the high resistance layer 4. A gate electrode 8 is formed on the exposed high resistance layer 4 to form a recess structure. A source electrode layer 6 and a drain electrode layer 7 are formed from the upper part of the contact layer 5 to the lower part of the side surface of the mesa part. A region of the contact layer 5 having neither the source electrode layer 6 nor the drain electrode layer 7 formed thereon and the high resistance layer 2 are coated with passivation layers 9a, 9b. Because the passivation layers 9a, 9b are composed of silicon oxynitride films, strain applied to the device can be made small.  <P>COPYRIGHT: (C)2003,JPO
