Abstract
An object of this invention is to provide a manufacturing method that, by using a general-purpose semiconductor fabrication process, can easily manufacture an ink jet print head in which energy generating elements are complicatedly installed in the ink path. To this end, the present invention comprising steps of providing a substrate having a removal projected portion, forming an energy generating element along the projected portion, forming a supporting member on the energy generating element, and forming a ink chamber by removing the projected portion from the substrate.
Claims10
A method of manufacturing an ink jet print head, wherein the ink jet print head includes an energy generating element for generating energy used for ejecting ink, a supporting member supporting the energy generating element, and an ink chamber communicating to an ink ejection orifice which is formed corresponding to the energy generating element, the method comprising the steps of:
- providing a substrate having a removal projected portion;
- forming the energy generating element so as to be supported with a side wall of the projected portion;
- forming the supporting member on the energy generating element;
- and
- forming the ink chamber by removing at least the projected portion from the substrate.
