Patent ID: 6969627

Claim:
A manufacturing method of a light-emitting diode (LED) comprising the steps of: providing a substrate; forming a pattern on a surface of the substrate for selective area epitaxy growth; forming a GaN film with a slant surface over the pattern using an epitaxy growth method, wherein the slant surface is naturally formed as a result of the properties of GaN and the upper surface of the GaN film is a plane with an area suitable for device users; and forming an LED structure on the GaN film, wherein the LED structure contains an n-GaN-series III-V family compound and a p-GaN-series III-V family compound, and p-GaN-series III-V family compound is in electrical communications with a p-type low-resistance ohmic contact electrode and the n-GaN-series III-V family compound is in electrical communications with an n-type low-resistance ohmic contact electrode for providing a forward bias; said LED structure being directly formed on said area of said upper surface of said GaN film by said method, so as to form an LED diode on the GaN film having a slant surface, which determines the size of the LED diode and increases light emission efficiency and yield.
