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 6):
The method of  claim 5 , wherein said step of fabricating said first gate dielectric layer further comprises steps of:\n depositing a dielectric layer for forming said epitaxial structure of N-face AlGaN/GaN; using the photoresist for defining the region of said first gate dielectric layer by exposure and development; performing wet etching using buffered oxide etchant for removing said dielectric layer outside the region of said first gate dielectric layer, and reserving only the region for forming said first gate dielectric layer; and removing the photoresist by using photoresist stripper.
