Dear SU 8 experts, I am trying to develop a 20 micron high SU8 channel (1.2 cm long) bonded between glass and silicon through the fluidic ports at either end of the channel. I am not able to develop the channel fully. I exposed for 20 s and developed in an ultrasonic bath. Could anyone share their experience/tricks/tips in solving this. Thanks for all the help. Prabhu
