Silicon (Si) wafer application

For dummy, for monitoring, for solar



*Thermal oxide film processing is also available.


*Wafer with various film (by PVD, CVD equipment) is available as well.


Please fill in “Other Requests” in the RFQ form.

Distinction between dummy and monitor

Specifications other than size, thickness are not mentioned, please specify dust not mentioned or dust free. (Wafer characteristics can be specified at delivery.)

  • Monitor wafer

Please specify on quotation request form.


*In order to promptly secure materials, we ask for cooperation in expanding the range of resistivity and thickness.

About regeneration processing

By carrying out regeneration processing (lap, etching, chemical polishing) on the wafers used, such as wafers used for transport tests and defective wafers generated during the process, the particle level and surface condition are restored to before use state. Please contact us as we can suggest the best regeneration method depending on the condition you are using.
