Technical Cost Modeling Applied to CVD Diamond Deposition
Abstract
IBIS Associates has completed its predictive spreadsheet models of chemical vapor deposition (CVD) diamond film fabrication. This report details the capabilities of the models, and shows cost sensitivities to product and process input parameters. The DC arcjet, microwave, and combustion flame CVD diamond deposition models, in addition to the CVD diamond finishing model, have been developed to maximize cost estimation flexibility. In doing so for deposition, inputs such as thermal conductivity, machine power, gas concentration, gas temperature, and reactor pressure have been provided in the model to predict the deposition growth rate, which is critical to the cost calculation. For the finishing model, inputs such as laser power, laser spot size, and laser frequency have been provided in the model to predict the diamond removal rate, which is also critical to the final cost calculation
