Embodiment 1
[0006] Embodiment one: to substrate (SiO 2 / Si) carry out pre-treatment, at first carry out the ultrasonic cleaning of acetone, 10wt% hydrochloric acid, deionized water to it respectively, the ultrasonic ultrasonic frequency is 40KHz, power 100W, and each cleaning time is 5 minutes; Put into KD-550 ethanol solution at 50-60°C for coupling for 10 minutes, the concentration of KD-550 is 1wt%; then place the substrate in a mixed solution of palladium chloride and hydrochloric acid at 50-60°C for 5 minutes, The concentration of palladium chloride and hydrochloric acid is 0.1g / L and 3.65g / L respectively, and the pH value of this mixed solution is adjusted to 5.0~6.5 by sodium hydroxide solution.
[0007] The solution is 20g / L nickel sulfate, 0.1g / L sodium molybdate, 20g / L sodium hypophosphite, 20g / L sodium citrate, 1g / L glacial acetic acid, 0.005g / L ammonium fluoride, 0.02g / L The composition is composed of sodium lauryl sulfate, sodium hydroxide solution and deionized water are ad...
Embodiment 2
[0009] For the substrate (SiO 2 / Si) carry out the previous processing as above.
[0010] The solution is 25g / L nickel sulfate, 0.2g / L sodium molybdate, 25g / L sodium hypophosphite, 25g / L sodium citrate, 3g / L glacial acetic acid, 0.004g / L ammonium fluoride, 0.03g / L The composition is composed of sodium lauryl sulfate, sodium hydroxide solution and deionized water are added dropwise to adjust the pH to 11, and the solution temperature is 85°C.
Embodiment 3
[0012] For the substrate (SiO 2 / Si) carry out the previous processing as above.
[0013] The solution is 30g / L nickel sulfate, 0.5g / L sodium molybdate, 30g / L sodium hypophosphite, 30g / L sodium citrate, 2g / L glacial acetic acid, 0.006g / L ammonium fluoride, 0.04g / L The composition is composed of sodium lauryl sulfate, sodium hydroxide solution and deionized water are added dropwise to adjust the pH to 12, and the solution temperature is 80°C.
