Patent ID: 8684493

Claim:
A droplet-discharging-head manufacturing apparatus that manufactures a droplet discharging head that includes a piezoelectric element formed by a lower electrode, a piezoelectric body as a laminated body of a plurality of ferroelectric layers, and an upper electrode laminated in this order, the droplet-discharging-head manufacturing apparatus comprising: a film forming unit that forms a ferroelectric precursor film on a silicon wafer having a conductive layer formed thereon; a heating unit that heats and bakes the ferroelectric precursor layer to form the ferroelectric layer; a cooling unit that cools the ferroelectric layer; a conveying unit that conveys a plurality of the silicon wafers one by one; and a control unit that controls the film forming unit, the heating unit, the cooling unit, and the conveying unit so as to repeat a series of processes including formation of the ferroelectric precursor layers by the film forming unit, heating of the ferroelectric precursor layers by the heating unit, and cooling of the ferroelectric layers by the cooling unit, for a predetermined number of times for each of the silicon wafers, one wafer by one wafer, wherein each of the film forming unit, the heating unit and the cooling unit performs processing on the plurality of the silicon wafers one wafer at a time.
