Abstract: In this paper, the substrate temperature field is modelled by using heat transfer theory to study the large area hot filament CVD system. In order to meet the requirement for proper magnitude and uniformity of the substrate temperature during the formation of the diamond film, the work to optimize the parameters of the substrate temperature field is performed. Sensitivity analysis is then used to search the key factor which deeply influences the substrate temperature field.

Key words: HFCVD, temperature field, diamond film, sensitivity
