发明名称 CVD method in vertical CVD apparatus using different reactive gases
摘要 A method of performing a CVD process on target substrates all together in a vertical CVD apparatus includes repeating, a plurality of times, first and second steps of supplying first and second reactive gases, respectively. The first reactive gas has a vapor pressure of 1.33 kPa or less, or a bond-dissociation energy of 250 kJ/mol or less. The second reactive gas has a vapor pressure of 2.66 kPa or more, and a bond-dissociation energy of 250 kJ/mol or more. The first reactive gas is supplied from a first delivery hole disposed at a bottom of the process chamber. The second reactive gas is supplied from a plurality of second delivery holes arrayed in a vertical direction at a position adjacent to edges of the target substrates entirely over a vertical length of the target substrates stacked at intervals.
