GoKawiilDiamond Foundry unveils 200mm single-crystal diamond wafer
Diamond Foundry, a lab-grown diamond company, announced it has produced the world's first 200mm single-crystal diamond wafer, a size comparable to those used in older-generation semiconductor fabs. Unlike polycrystalline diamond, single-crystal diamond retains high thermal conductivity while remaining electrically insulating, though the current sample is unpolished and requires further processing before use by chipmakers. The company also presented projections suggesting a 300mm version could be achievable before 2030.
