Okamoto is a leading manufacturer of precision grinding and polishing tools since 1935.
Grinding tools are used in applications of wafer manufacturing, SOI, TSV, MEMS, thin wafers down to 25 um, bonded wafers, bumped wafers, solar ingot grinding, quartz, sapphire, SiC, GaAs, InP and more. Polishing tools used with CMP technology for high throughput and high accuracy. All tools are available up to 300mm. For thin wafer applications, grind/polish systems can be integrated with a mounter, DAF, and detaper equipment as a complete in-line system.
Okamoto is ISO9002 certified.
