How to solve the problem of poor adhesion on silicon dioxide?

Try chromium change, slower when plating

Have you tried to deal with your silicon?For example, erosion to increase surface roughness, or introduce functional groups for surface modifications. Don't ask me for specific, because I don't know personal opinion, for reference only

Generally, the transition layer is used with titanium membrane, and the adhesion is very good.It may be because of steamed plating. If you have conditions, you can try sputtering gold -plated film

Generally, the adhesion is also available after adding the adhesion layer. Do you have the problem of checking the substrate and cleanliness.In addition, if you want to be adhesive, you can use sputtering. If the gold layer is too thick, it will be stressful, which will indirectly affect the adhesion.And whether you have observed whether to fall off, which part of it is falling off, silicon oxide and TI layers fall off or fall off with the gold layer. This is very important to help you analyze where the problem is.I do n’t know who you use your background. Is the gold -plated process operated by yourself?
