Claim 7:
8. A nitride-based device, comprising:
an epitaxial structure including a substrate and an epitaxial layer disposed on said substrate, said epitaxial layer having a buffer layer, a channel layer, and a barrier layer disposed on said substrate in such order;
an isolation trench formed in said epitaxial structure, so as to divide said epitaxial structure into an active region and an electrostatic discharge protection region outside said active region;
a source electrode, a drain electrode and a gate electrode being disposed on said active region of said epitaxial structure and spaced apart from each other;
a field plate that is disposed on said active region of said epitaxial structure and spaced apart from said source electrode, said drain electrode and said gate electrode; and
a first p-type nitride layer and a metal layer formed on said barrier layer of said electrostatic discharge protection region of said epitaxial structure in such order.
