Hi, I am searching for some information or guidelines when bonding silicon nitride to silicon, silicon dioxide or silicon nitride. I found an article "Spontaneous direct bonding of thick silicon nitride" S Sanchez, C Gui and M Elwenspoek J. Micromech. Microeng. 7 (1997) s111-113 which addresses the importance of surface smoothness with CMP before bonding. Is there any other good references or guidelines I could use before proceeding with my bonding experiments. Regards, Marcus Törndahl Ps. Thank you for a most interesting and educating forum Ds. _____________________________________________ Marcus Törndahl (PhD student, MScEE) Department of Electrical Measurements/LTH Lund University Ole Römers väg 3 SE-221 00 Lund Sweden
