Alumina Ceramic Sheet


Alumina Wafer Polishing Plate

alumina wafers for thin film circuits,alumina wafers for semiconductor processing,sensor component substrates

We are able to manufacture alumina wafers up to a maximum size of φ300mm (φ12 inch).
With a high density and few pores, it is possible to form fine circuit patterns.
We also handle substrates with fine rounded/square holes or slits, as well as polished substrates.
