Processes for forming an actuator having a curved piezoelectric membrane are disclosed. The processes utilize a profile-transferring substrate having a curved surface surrounded by a planar surface to form the curved piezoelectric membrane. The piezoelectric material used for the piezoelectric actuator is deposited on at least the curved surface of the profile-transferring substrate before the profile-transferring substrate is removed from the underside of the curved piezoelectric membrane. The resulting curved piezoelectric membrane includes grain structures that are columnar and aligned, and all or substantially all of the columnar grains are locally perpendicular to the curved surface of the piezoelectric membrane.

A method of manufacturing a liquid ejection head in which a pressure chamber for storing an ejection liquid is connected with an ink supply channel through a restrictor, includes the steps of: forming first spaces for the liquid supply channel and the pressure chamber in a silicon substrate by performing anisotropic etching on a surface of the silicon substrate, the surface of the silicon substrate being parallel to a Si(110) plane, each of the first spaces being defined by two vertical walls and two inclined walls, each of the two vertical walls being parallel to a Si(111) plane that is perpendicular to the surface of the silicon substrate, each of the two inclined walls being parallel to a Si(111) plane that is inclined with respect to the surface of the silicon substrate; then forming an etching protection film on the silicon substrate, the etching protection film protecting the silicon substrate from being etched; then forming an opening corresponding to a second space for the restrictor in the etching protection film; and then performing anisotropic etching on the surface of the silicon substrate through the opening of the etching protection film to form the second space in the silicon substrate, the second space for the restrictor being defined by two inclined walls each of which is parallel to the Si(111) plane that is inclined with respect to the surface of the silicon substrate, the second space connecting the first spaces for the liquid supply channel and the pressure chamber with each other.
