摘要： A method of making a printhead includes forming a channel member by providing a mold having a top portion having peaks and valleys and by tape casting a slurry of piezoelectric material into the mold and onto the peaks and valleys of the top portion of the mold to form a tape cast member having a bottom surface with peaks and valleys and a flat top surface and removing the tape cast member. After removing the tape cast member, the top surface of the tape cast member is embossed so as to provide peaks and valleys in opposite sides of the tape cast member wherein the valleys in the top surface are disposed in an offset relationship to the peaks in the bottom surface. Thereafter, the embossed tape cast member is poled to align the electrical dipoles within the piezoelectric material; and a coating of conductive material is formed over the top and bottom surfaces of the tape cast member and then cutting grooves through conductive coating into the top surface in the valleys of the tape cast member to form a channel member. Finally, an orifice plate is provided over top surface of the channel member and a substrate over the bottom surface of the channel member.
