I n the ma nufacturing process of a ny mecha nical parts with spatially varied characteristics, controlling a characteristics distribution is important depending on its intended use. In the electroplating process, it is desirable to form a thin film with different thickness on different local positions on the base material. Therefore, it is necessary to achieve a specific profile of film thickness distribution. Although the conventional robust parameter design have been used to make a uniform film, it is difficult to design a custom profile of film thickness distribution under various constraints. Considering this situation, we propose a parameter design method to control a spatial distribution in a custom profile with a parameter design. Three regression parameters corresponding to feature quantities of a distribution are designed as multi-objects. The effect of the method will be verified for an electric plating process as a case study. Also an application to control the profile based on this approach will be introduced.
