摘要： A method of forming a piezoelectric layer includes: a drying step for forming at least one ferroelectric precursor film on a lower electrode of a substrate and drying the ferroelectric precursor film; a degreasing step for carrying the substrate into a region facing a hot plate heated to a certain temperature and for degreasing the ferroelectric precursor film in a state where the substrate is supported by a proximity pin; and a baking step for further baking the degreased ferroelectric precursor film to form the degreased ferroelectric precursor film into a ferroelectric film. The piezoelectric layer is formed by repeating the drying, degreasing, and baking steps for the ferroelectric precursor film in a predetermined number of cycles. The degreasing step includes a step of adjusting a heating temperature of the ferroelectric precursor film by adjusting a distance between the hot plate and the substrate and by lowering a temperature of space on an opposite side of the substrate from the hot plate.
