Abstract
The present invention provides a pattern of elimination of passivation photoresist layer avoiding PR extrusion in the alloy process with residual of photoresist and stripper, including the following steps: first removal of part of the passivation photoresist with dry etching, followed by the removal of the rest of the photoresist layer with wet etching. Then, using proper solvent for one or more surface layer cleaning to remove the residue before quick dump rinse, QDR for liquid ion.
