| titleOfInvention | A kind of minimizing technology of LED electrode structure |
| abstract | The present invention relates to a kind of minimizing technologies of LED electrode structure; pass through the preliminary adhesiveness reduced between metal electrode layer and P-GaN layers of physics ultrasound; then sealer is eroded using hydrofluoric acid, is finally removed in metal electrode layer using the mixed solution of hydrochloric acid and hydrogen peroxide using chromium, aluminum metal as all metals (including titanium, golden beryllium, gold, platinum, silver, nickel, germanium) of bottom.The present invention mainly utilizes metallic aluminium to react with diluted acid, the relatively thin chromium band of the bottom is fallen under specific environment, it is succinct also step of the present invention to be detached from falling off for aluminium positioned at the metal of aluminium top layer, it is easy to operate, under conditions ofs without using special chromium corrosive liquid, golden corrosive liquid etc., under the premise of being completely secured injury-free, the fully effective corrosion for realizing entire metal electrode layer is done over again, LED electrode body structure surface after corrosion cleaning is clean, no any metallic residue, layers of chrome counterdie residual. |
