Hi, ths is dlee from Ut austin. I try to bond two piece of PDMS layer toghter with O2 RIE. The paramter is O2 10sccm, 45 mtorr, 100watts. but bonding result is bad. I also try O2 20sccm, 70 mtorr and 75 watts, also the result is noy good. In my case, i need high strength bonding, at the least the bonding can stand 20-30 psi. I read some paper. It was said O2 RIE bonding can stand 50psi pressure. I am not sure what is wrong with my process. Anybody has suceed to achieve such good bonding strength (>30psi), any suggestion will be appreciated.
