| 20090302502 | PROCESS OF PRODUCING LIQUID DISCHARGE HEAD - Provided is a process of producing a liquid discharge head having a substrate, a passage-forming member, and a patterned layer. The process includes providing a resin layer on a substrate; providing a resist pattern on the resin layer for patterning the resin layer; forming a patterned layer by patterning the resin layer using the resist pattern as a mask; providing a layer for forming a passage pattern having a shape of passage on the resist pattern lying on the patterned layer; forming a passage pattern by patterning the layer for forming a passage pattern; removing the resist pattern; providing a passage-forming member so as to cover the passage pattern and the patterned layer; and removing the passage pattern to give the passage. | 12-10-2009 |
| 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 |
| 20100216264 | METHOD OF MANUFACTURING A SUBSTRATE FOR A LIQUID DISCHARGE HEAD - A method of manufacturing a substrate for a liquid discharge head, the substrate being a silicon substrate having a first surface opposed to a second surface, the method comprising the steps of providing a layer on the second surface of the silicon substrate, wherein the layer has a lower etch rate than silicon when exposed to an etchant of silicon, partially removing the layer so as to expose part of the second surface of the silicon substrate, wherein the exposed part surrounds at least one part of the layer; and wet etching the layer and the exposed part of the second surface of the silicon substrate, using the etchant of silicon, to form a liquid supply port extending from the second surface to the first surface of the silicon substrate. | 08-26-2010 |
| 20110151598 | METHOD FOR MANUFACTURING A SUBSTRATE FOR LIQUID-EJECTING HEADS AND A LIQUID-EJECTING HEAD - A method for manufacturing a substrate for liquid-ejecting heads includes etching a surface of a silicon substrate using a first etchant, with a silicon oxide layer as a mask, to form a depression as a part of a liquid supply port, and subsequently etching at least the silicon oxide layer and the thickness sandwiched between the depression and the etched surface of the silicon substrate with a second etchant to form the liquid supply port. | 06-23-2011 |
| 20110183448 | LIQUID COMPOSITION, METHOD OF PRODUCING SILICON SUBSTRATE, AND METHOD OF PRODUCING LIQUID DISCHARGE HEAD SUBSTRATE - A liquid composition used to carry out crystal anisotropic etching of a silicon substrate provided with an etching mask formed of a silicon oxide film with the silicon oxide film used as a mask includes cesium hydroxide, an alkaline organic compound, and water. | 07-28-2011 |
