Hi, I am trying to use gold metal lines on p+ and n+ silicon surface. I am in split decision between using TiW/TiW-N or Ti/Ti-N for underlying diffusion barrier/adhesion layer. Could someone tell me what's advantage of using particular diffusion barrier/adhesion layer for gold metallization? Reference books or articles are also appreciated.
