Title: Field effect transistor and its manufacture
Inventor: KONO JUNKO
IPC: H01L21/338
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To improve the gate-drain withstand voltage of a field effect transistor while the highly reliability of the transistor is secured and the high output current of the transistor is maintained by providing a surface oxide layer by partially oxidizing the element surface between gate and drain electrodes. SOLUTION: A buffer layer 12 and a channel layer 13 are successively laminated upon a semi-insulating gallium arsenide substrate 11. A source electrode 14 and a drain electrode 15 which is joined to the electrode 14 in an ohmic contact are formed on the channel layer 13, and a gate electrode 16 which controls the drain current which flows through the channel layer 13 is formed between the electrodes 14 and 15. After the electrodes 14 and 15 and channel layer 13 are formed, the electrodes 14 and 15 and layer 13 are covered by growing an insulating film composed of an oxide film or nitride film on the electrodes and layer 13 as a protective film. Since the surface of the channel layer 13 is oxidized between the gate and drain electrodes 16 and 15, a depletion layer increases and the effective carrier impurity concentration decreases below the oxidized surface. Therefore, the electric field concentration between the gate and drain electrode 16 and 15 can be relieved.
