Among the surface finishing processes lapping and polishing are very important for manufacturing and fabricating semiconductor and optoelectronic devices. For copper, the quality of these processes has a critical role in the performance of heatsinks. In this paper an intermediate process named “inter-polishing” was introduced. This process placed after lapping and before polishing. The result is obtaining a surface with more flatness and less hardness that are key parameters to achieve an ideal surface after polishing.
