Abstract
A light-emitting diode has a metal mesh pattern formed on an active layer without a transparent oxide conductive layer formed in between is disclosed. The mesh pattern is formed by using ion bombardment a metal layer so that myriad pits formed into the exposed portion of the active layer served as light emitting centers.
Claims6
A method of forming a light-emitting diode, comprising:
- providing a semi-product of a light-emitting diode from a bottom thereof formed with an active layer, said active layer having a lower cladding layer, an intrinsic layer and an upper cladding layer;
- forming a metal layer on said upper cladding layer;
- patterning said metal layer by using a mask and an ion bombardment technique so as to form a mesh pattern having myriad pits into the exposed surface of said upper cladding layer from said mesh pattern.
