Immersion deposition of cu on steel plate
WitrynaFigure 4 shows the microhardness of the Cu deposit with respect to the current voltages. The figure shows that the mean hardness of the plated Cu increased significantly … Witryna4 mar 2004 · Preliminary results show that Cu deposition on Si/TaN wafers can also be performed with good adhesion using this bath sequence, but longer immersion time is required in the galvanic displacement bath. The nature of the Ta aqueous interface is critical to obtaining adequate adhesion of the Cu deposit.
