Abstract

The spin-on hard mask material for photo resist in semiconductor industry is usually obtained from a small-scale batch process. To obtain high purity products requires multiple-step purification processes, during which a large amount of organic solvent waste is emitted. In this study, a process for regenerating high purity solvent was proposed and the economic efficiency of the proposed process was analyzed. Also, a sensitivity analysis was performed to analyze the changing economics regarding the main variables. From the analysis, the break-even point can be achieved within one year for different cases considered. On the basis of 4-year operation, the profit margins for each case were determined and compared. It is concluded that the waste solvent regeneration process for spin-on hard mask material production in semiconductor industry is feasible and recommended.
