20090183368 | METHOD OF MANUFACTURING INK JET RECORDING HEAD - A method of manufacturing an ink jet recording head includes the steps of: forming an adhesive layers and the side walls of a flow path on a substrate; pasting a dry film, which is a part of a flow path forming member, on the side walls; and forming discharge ports in the layer. | 07-23-2009 |
20100147793 | METHOD FOR PRODUCING LIQUID DISCHARGE HEAD - The present invention provides a method for producing a liquid discharge head including a silicon substrate having, on a first surface, energy generating elements, and a supply port penetrating the substrate from the first surface to a second surface, which is a rear surface of the first surface of the substrate. The method includes the steps of: preparing the silicon substrate having a sacrifice layer at a portion on the first surface where the ink supply port is to be formed and an etching mask layer having a plurality of openings on the second surface, the volume of a portion of the sacrifice layer at a position corresponding to a portion between two adjacent said openings being smaller than the volume of a portion of the sacrifice layer at a position corresponding to the opening; etching the silicon substrate from the plurality of openings and etching the sacrifice layer. | 06-17-2010 |
20110107598 | LIQUID EJECTION HEAD AND METHOD FOR MANUFACTURING LIQUID EJECTION HEAD - A liquid ejection head and a method of forming the same. The liquid ejection head includes a substrate, an ejection port, a liquid channel, and a supply port. The substrate has, above one side thereof, an energy generating element configured to generate energy used to eject liquid. The ejection port, from which a liquid is ejected, is located at a position corresponding to the energy generating element. The liquid channel communicates with the ejection port and penetrates the substrate from the one side to another side of the substrate. The supply port communicates with the liquid channel. The substrate has a projecting layer extending inward of an inner peripheral portion of an opening in the supply port in the one side, and the projecting layer and the energy generating element are formed of the same material. | 05-12-2011 |
