Abstract:
The present invention provides an epitaxial structure of N-face group III nitride, its active device, and the method for fabricating the same. By using a fluorine-ion structure in device design, a 2DEG in the epitaxial structure of N-face group III nitride below the fluorine-ion structure will be depleted. Then the 2DEG is located at a junction between a i-GaN channel layer and a i-Al y GaN layer, and thus fabricating GaN enhancement-mode AlGaN/GaN high electron mobility transistors (HEMTs), hybrid Schottky barrier diodes (SBDs), or hybrid devices. After the fabrication step for polarity inversion, namely, generating stress in a passivation dielectric layer, the 2DEG will be raised from the junction between the i-GaN channel layer and the i-Al y GaN layer to the junction between the i-GaN channel layer and the i-Al x GaN layer.

Claim (Index 13):
The method for fabricating a hybrid N-face AlGaN/GaN Schottky barrier diode with polarity inversion of  claim 12 , characterized in steps of:\n using the metal vapor deposition and metal lift-off methods to form a first source electrode and a first drain electrode in said left region and a cathode electrode in said right region; and performing a 700\u02dc900\u00b0 C. thermal treatment for 30 seconds for enabling said first source electrode, said first drain electrode, and said cathode electrode to become ohmic-contact electrodes.
