I would like to know how to develop recipes for descum and ashing of 3000PY and 1813 resists on Alumina and MgO substrates using any type of equipment. I know both processes are used for residue cleaning but I would like to know how to develop the recipe myself. In other words, how to select the power level (W), Volumetric Flow Rate (sccm), duration (minutes), pressure (mT), etc. as applicable to a system.
