Contracted Processing /
Development Projects

We undertake contracted processing / development projects for various kinds of materials in order to comply with a variety of requests from our customers:

Precision polishing / micromachining

Drawing on our experience in polishing special materials such as sapphire and diamond substrates, we undertake precision polishing of various materials in both small yield and mass production quantities.

Single crystal growth contracted development

We have extensive experience in mass producing sapphire substrates using the EFG method, and have also engaged in growing diamond and gallium oxide crystals. We are also well equipped and knowledgeable in crystal growing methods other than EFG, and with this expertise, we are undertaking contracted R&D and support business for creating new single crystal materials.
We can create a proposal for mass production crystal growth at lower cost by growing crystals in a controlled shape optimized for various applications.

If you are interested in crystal growth development and/or new material development, please do not hesitate to contact us.
