Hi Abdou, The dispensing is done using a syringe , distributing manually the SU-8 over the whole wafer surface beginning from the center towards the edge. When completely covered, the spinner is started. To fill the syringe (10 ml), I open it at the back and pore the SU-8 into it directly from the bottle.
