摘要:
A method of making a liquid discharge head which includes a nozzle to discharge liquid, a pressure chamber communicating with the nozzle, a pressure chamber substrate to form surfaces of the pressure chamber, and a piezoelectric actuator to apply pressure to liquid in the pressure chamber having a lower electrode, a ferroelectric film, and an upper electrode, includes a silicon wafer supplying process, a position adjustment process, a surface treatment process to reform a surface of the lower electrode, a liquid applying process to apply ferroelectric precursor on the lower electrode by an inkjet method, a heating process to heat the ferroelectric precursor film, and a cooling process. A series of processes from the position adjustment process to the cooling process is iterated to form a ferroelectric film having a predetermined thickness. The series of processes is performed with certain waiting times inserted between key processes.
