20120097637 | METHOD OF MANUFACTURING SUBSTRATE FOR LIQUID DISCHARGE HEAD - Provided is a method of manufacturing a substrate for a liquid discharge head including a first face, energy generating elements which generate the energy to be used to discharge a liquid to a second face opposite to the first face, and liquid supply ports for supplying the liquid to the energy generating elements. The method includes preparing a silicon substrate having, at the first face, an etching mask layer having an opening corresponding to a portion where the liquid supply ports are to be formed, and having first recesses provided within the opening, and second recesses provided in the region of the second face where the liquid supply ports are to be formed, the first recesses and the second recesses being separated from each other by a portion of the substrate; and etching the silicon substrate by crystal anisotropic etching from the opening of the first face to form the liquid supply ports. | 04-26-2012 |
20130026130 | METHOD OF MANUFACTURING LIQUID EJECTION HEAD SUBSTRATE - A liquid ejection head substrate is manufactured by forming a wiring pattern on one surface of a substrate, forming an etching mask layer on the other surface of the substrate, forming a positioning reference mark on the etching mask layer by means of a laser, forming an opening pattern groove running through the etching mask layer and having a bottom in the inside of the silicon substrate, using the positioning reference mark, and forming a liquid supply port running through the silicon substrate by etching the silicon substrate from the opening pattern groove to the one surface by means of crystal anisotropic etching. | 01-31-2013 |
