The group's principal activity is to develop, manufacture and supply polishing slurries to the semiconductor industry for usage in chemical mechanical planarization. the polishing slurries are used in chemical mechanical planarization process to remove excess materials that are deposited on multiple layers that are built upon silicon wafers. cmp enables ic device manufacturers to produce smaller ic devices with greater density, both of which improve the performance and capabilities of the device. the group markets the products through independent distributors and other industry suppliers. intel, marketech and takasago are the group's major customers.
