Dear everyone: Does anyone who has the available process to do the glass-glass bonding? I have tried several times with the glass-glass bonding, and I have used RCA1# solution and O2 plasma activation for assistant, but finally I can't realize the bonding. The process temperature is about 200~300 ℃ ,and the bonding pressure is about 2000N, 6' Pyrex7740 glass wafer, 500um thickness. The bonding machine is EVG520. Thanks to any help. Regards. Evan J
