Since 2004
For Optics, Semiconductors, MEMS and Biochemical reserachers
Optostar Ltd. is a Japan-based international material supplier, providing optoelectronic and semiconductor substrate wafer products since Y2004. We pride ourselves on being a speedy and cost-effective supplier in world's wafer(substrate) market. Thanks to increasing demand for speedy fabrication in substrate wafer products for semiconductor, optoelectronic, MEMS and other applications, we are greatly expanding our exporting sales in 2- to 8-inch fused silica (quartz glass) and borosilicate glass wafers as well as single-crystal items like sapphire wafers. Nowadays, we provide very thin polished glass, fused-silica and silicon wafers mainly for research applications. By providing those high-precision-fused-silica, glass, and crystal wafers, we contribute to the international development of the state-of-the-art devices in optoelectronic, semiconductor, MEMS and other industries.
