Through-hole wafers

We have drill and laser processing capability. Our NAPHIA™ through-hole sapphire wafers have high surface quality equivalent to that of bare sapphire wafers, and are suitable for semiconductor processing. We can make through-hole wafers not only from sapphire, but also from other materials (ceramics, silica glass, etc.).
