• We are sharing the quality inspection results of the CVD graphene currently used in our products with our customers.
• Before purchasing, please review the quality of the CVD graphene applied to the current CVD graphene on Si wafer product and make your ordering decision accordingly.
• Please note that the quality may vary if the transfer process is carried out directly by the customer or if additional post-processing is applied.
• Production Date of CVD Graphene on Cu Foil : 2026. 03. 27.
• CVD graphene on SiO2
1) Transfer method : Vacuum transfer
2) Transfer area : 4-inch Si wafer (full coverage)
3) SiO2 thickness : 90nm
• Quality check method
1) Optical microscope @ RT - X600 (magnification)
2) Raman (Single & mapping) @ RT – 532nm / 5mW
3) 4-points probe for sheet resistance @ RT - CMT-SR2000N
1) Optical image of CVD graphene after transfer
2) Raman measurement results
3) Sheet resistance measurement results
