摘要: The present invention is a method for using a single SiN layer as a passivation film. The single layer SiN can be strengthened to withstand stress by adjusting the process parameters during formation of the SiN layer. In general, the process can be changed by increasing the low frequency power 5% during the deposition. Alternatively, the pressure of the SiN deposition may be decreased about 20% in pressure.
