  • Electrolytic method for photoresist stripping
    Publication number: 20050167284
    Abstract: Photoresist stripping is performed by having a piecepart with a conductive layer that patterned by the photoresist immersed in a neutral solution. A voltage potential is applied to induce a current between the conductive layer and a counter electrode in neutral solution bath at a specified current density. After a short period of time, on the order of minutes, the photoresist is lifted off the piecepart. The piecepart is then removed from the bath, rinsed and dried.
