Hi

Glass to glass anodic bonding will not work. one solution is that u
sputter  a thin film of silicon on the top glass substrate. and then
apply negative bias to the bottom glass and do the anodic bonding. may
be this work. Another solution is at high pressure glass to glass
fusion bonding .
May be this would be helpful.
bye
