Au-Au thermo-compression wafer bonding

Hi Domenico,

Can you please give some references about your work with Thiol for bonding?

I experimented with around 12lbs weight at 100 degrees C for an hour. It
didn't work. I am just using Si wafers with Au-Au layers, which are plasma
activated (1 minute of plasma etching just before bonding). Then I bond
them at room temperature and then anneal them in an oven for sometime. I
will surely try the same at 200 degrees C.
