摘要：

In the study of electroless nickel (EN) plating on n-type (100) silicon wafers, a relatively low-temperature alkaline plating process is developed. Further experiments show that simple ethanol pretreatment of the substrate is practicable for obtaining an EN layer with a good adhesion strength of about 9.8 to 14.7 MPa. Both sodium tungstate and sodium fluoride can be used to decrease the threshold plating temperature from near 80 degrees C to 65 degrees C. The phosphorous content of the as-plated layer is slightly higher than 7 wt.%.
