Claim Text:
1. A nitride-based semiconductor diode comprising: a substrate; a first semiconductor layer disposed on the substrate; a second semiconductor layer disposed on the first semiconductor layer, the first and second semiconductor layers including a nitride-based semiconductor, and a first portion of the second semiconductor layer having a thickness thinner than a second portion of the second semiconductor layer; an insulating layer disposed on the second semiconductor layer; a first electrode overlapping the first portion of the second semiconductor layer when viewed from a plan view and forming an ohmic contact with the first semiconductor layer and the second semiconductor layer; and a second electrode separated from the first electrode, the second electrode forming an ohmic contact with the first semiconductor layer and the second semiconductor layer, wherein the first portion of the second semiconductor layer is a recess, and the first electrode fills the recess with the insulating layer therebetween.
