Abstract: A method for roughening silicon substrate surface includes providing a silicon substrate having a waiting-for-etching surface, the waiting-for-etching surface has a plurality of first and second areas; forming a plurality of covering bumps on the first areas, and a gap is formed between each of the covering bumps and each of the first areas; and etching the waiting-for-etching solution by a anisotropic etching solution. The anisotropic etching solution permeates into each of the first areas through the gap to lead the etching time of the first areas is shorter than that of the second areas, so the waiting-for-etching surface becomes a undulate surface having a plurality of undulate structures because the etching depth of the first areas is smaller than that of the second areas.

Abstract: An electroless plating process includes providing a semiconductor substrate which has a substrate and a copper pillar disposed on the substrate; providing a tin-silver plating solution includes 0.1-50 wt % tin and 1×105-2 wt % silver; and performing a reduction reaction, wherein the semiconductor substrate is disposed in the tin-silver plating solution for making tin and silver of the tin-silver plating solution deposit jointly on the copper pillar surface to form a tin-silver co-deposition layer. The tin-silver co-deposition layer is able to enhance the coupling strength between the copper pillar of the semiconductor substrate and the other semiconductor substrate and is also able to reduce the time and cost of the process performing tin-plating and silver-plating separately.
