The method of the present invention of manufacturing a nozzle plate for an ink jet recording head comprises a first step of forming a layer of a resin comprising a benzene ring on a metal substrate, a second step of patterning the layer of the resin by means of excimer laser and partially exposing the metal substrate, a third step of forming a metal layer having a thickness smaller than that of the resin layer on the exposed surface of the metal substrate by electroforming, and a fourth step of separating the metal layer from the metal substrate and the resin layer.

Method of manufacturing nozzle plate for ink jet recording head, ink jet recording head comprising such nozzle plate, and ink jet recording apparatus comprising such head

A method for manufacturing an ink jet recording head, which is provided with orifices for liquid discharge use, nozzles communicated with the orifices, electrothermal converting members arranged in the nozzles to form bubbles in the liquid by providing thermal energy for it, the liquid chamber communicated with the nozzles to supply liquid to the nozzles and a substrate having the electrothermal converting members provided therefor, comprises the steps of preparing the substrate to be a silicon substrate having (,) plane or (,) plane crystal axes therefor, forming organic resin layer at least in the liquid chamber on the silicon substrate, then, removing by means of anisotropic etching a part of the liquid chamber formation portion of the substrate from the reverse side of the formation surface of the organic resin layer and forming an elastic member portion formed by the membrane of the organic resin layer in the liquid chamber. With the method of manufacture thus arranged, it is possible to provide an ink jet recording head capable of performing stable discharges for a long-term use with the incorporation of such elastic member portion in the liquid chamber to absorb the pressure vibration caused by the performance of ink discharges and to suppress the resultant vibrations of menisci at the discharge ports.

Method of manufacture of ink jet recording head with an elastic member in the liquid chamber portion of the substrate

A method for manufacturing an ink jet printing head comprises a step of joining together a base board having ink discharge pressure generating elements, which also forms the bottom of a plurality of ink paths, and a ceiling plate that forms the ceiling portion of the plurality of ink paths in order to provide an ink jet printing head. In this method, either one of the joining portions between the base board and ceiling plate is Si and the other one of them is metal, and after each of the joining portions is irradiated by an energy particle, the base board and the ceiling plate are made in contact and cold joined by the application of cold activation. With the method of manufacture thus provided, it is possible to make the intensity of joint between the ceiling plate and base board firmer so as to eliminate any gaps between them, hence preventing the creation of cross talk phenomenon, and the degradation of quality of printed images as well.
