Palladium seed etchant
WebThe Activator is an immersion reaction bath that displaces copper and seeds it with palladium. The palladium initiates the subsequent autocatalytic nickel plating step. Electroless Nickel. The electroless nickel is an autocatalytic process. The nickel layer acts as a diffusion barrier that is solderable or aluminum wire bondable. Immersion Gold. Webhowever, a thin and continuous seed layer was necessary to provide an effective path for electric current [8]. The quality of electroplated copper films was strongly dependent on the step coverage of seed layers. Recently, the method of palladium (Pd) activation on TaN x barriers for autocatalytic electroless copper deposition was continuously ...
