Start with the process window. The required chemistry, purity, particle population and surface state are defined by the manufacturing step and downstream qualification route. Process requirement: deposition · planarisation · patterning Material controls: purity · particle size · agglomeration · surface chemistry · crystal phase Development route: K1 · K10 · K100 · AMLearn Tell us the front end material requirement and qualification constraint Share the process step, target material function, purity and contamination limits, current scale, required volume and the performance constraint that is preventing progress. AM can then assess where controlled synthesis, particle engineering and reproducible scale up can contribute.
