Hi, I'm working with SU-8 10 and am having some adhesion and developing problems. We are trying to obtain 30 micron deep features, but when developing, the features either tend to all come off the slide or not develop fully down to the glass. It seems like exposure time is not a problem as adhesion of the SU-8 to the glass slide is. We are playing around with baking methods and times. Does anyone have any advice about baking such as hot plate vs. oven, temp and time, and prebaking the glass slides to dehydrate them. Any help would be greatly appreciated. Thanks Kelvin Liu
