Patent ID: 7576008

Claim:
A method for manufacturing an optoelectronic semiconductor device having a p-n junction diode, comprising the steps of: (a) etching at least one surface of the p-n junction diode in a depth direction to form a plurality of continuous, isolated or mixed type electrode pattern grooves with a certain array; and (b) filling the formed grooves with a conductive ink containing a transparent conducting particle through an inkjet and then performing heat treatment to form a buried transparent electrode wherein the electrode is manufactured on a single stage through a unified manufacturing process using (a) a laser device for forming one or more electrode pattern grooves with a certain array on one or both surfaces of a p-n junction diode; and (b) an apparatus for manufacturing an optoelectronic semiconductor device with a built-in inkjet device for filling the formed grooves with a conductive ink containing a conductive particle to form an electrode pattern.
