Abstract:
A method of fabricating a semiconductor device employing electroless plating including wafer backside protection during wet processing is disclosed. The method includes the steps of laminating a wafer back side and a frame with a protective tape, applying a protective coating to a peripheral portion of the wafer and an adjoining exposed area of the protective tape, the protective coating, protective tape, and wafer forming a protected wafer assembly, curing the frame-supported protective coating, cutting the protected wafer assembly from the protective tape surrounding the protective coating, wet processing the protected wafer assembly, laminating the protected wafer assembly with a second tape, dicing the wafer, and picking up the die from the protective tape.
