The typical sizes of silicon wafers used for semiconductor devices in the industry are from 200mm(8-inch) to 300mm(12-inch). Nevertheless, many university or corporate researchers still have a need for smaller silicon wafers (less than 100mm(4-inch) in diameter); therefore, we specialize in sales for those 2- to 6-inch silicon wafers.

The surfaces of the silicon wafers can be polished at epitaxy-ready grade. Please send the necessary specifications if you need wafers other than standard varieties listed.
