Beschreibung
Zusammenfassung:	[Object] A refractive index and/or uniformity of distribution of a deposition rate of a nitride film falls within a predetermined numerical range, and stress of the nitride film is well controlled. [Solution] The invention provides a nitride film manufacturing apparatus 100 that forms a nitride film 70 (70a) on a substrate 20 provided in a chamber 30 by a plasma CVD technique. Specifically, the nitride film manufacturing apparatus 100 includes a controller 39 for calculating a first period for applying first high-frequency power having a relatively high frequency and a second period for applying second high-frequency power having a relatively low frequency in order to obtain desired compressive stress or tensile stress (including a case where the stress is zero) of the nitride film 70 (70a), based on distribution of a refractive index of the nitride film and/or distribution of a deposition rate of the nitride film, the distribution falling within a predetermined numerical range and being obtained using the first high-frequency power and/or the second high-frequency power applied independently for forming the nitride film 70 (70a).
