Abstract:

IBIS Associates has developed its predictive spreadsheet model of combustion flame chemical vapor deposition CVD diamond film fabrication. This report explains the assumptions for combustion flame deposition theory, and shows preliminary results of the economics of this CVD diamond process. For this report and the results contained herein, it is assumed that the transport theory model which predicts growth rates in the CVD diamond technical cost model closely predicts actual growth rates for the combustion flame technology and that the input values for variables such as the gas flow rate and substrate diameter are physically achievable. With this assumption as the basis for cost estimation, the cost of producing 1,000 planarized polycrystalline diamond wafer at one millimeter thick is estimated in the long run to be 73 per square centimeter for the combustion flame technology
