A method for precisely manufacturing a liquid supply orifice of an ink-jet recording head, even if a masking material includes pinholes which may affect the forming of the ink supply orifice, is provided. The substrate face provided with a mask used for forming the ink supply orifice has an area covered with the mask for anisotropic etching, the area consisting of a part provided with OSF layers and a part not provided with the OSF layers which are determined by considering the amount of a side etching.

An ink jet head includes a substrate having a flow path construction member constructing a plurality of discharge ports for discharging ink and a plurality of ink flow paths corresponding thereto, and a plurality of energy generating elements corresponding to the plurality of discharge ports. The substrate has an ink supply port for supplying ink to the ink flow paths. The ink supply port includes a first liquid chamber disposed on a plane on which the energy generating elements are formed, and having a grooves with island-shaped columns left, and a second liquid chamber disposed on the opposed plane, and having a plurality of through holes partitioned at positions corresponding to the island-shaped columns. In the ink jet head, the island-shaped columns and a partition wall for the through holes are left as a beam construction section, thereby improving a mechanical strength of a semiconductor substrate. Also, the first liquid chamber has a groove with island-shaped columns left, thereby enabling ink to be adequately supplied from the ink supply port to the discharge ports.

摘要:
The present invention permits to manufacture, with low cost and good through-put, a liquid discharge recording head in which a nozzle plate is formed from inorganic material. In the liquid discharge recording head according to the present invention, a nozzle plate formed from inorganic material is stacked on a front surface of a silicon substrate including heat generating resistant members for generating energy for discharging liquid and an electric circuit for driving the heat generating resistant members. The liquid can be supplied from a liquid supply port extending through the silicon substrate to flow paths provided between the silicon substrate and the nozzle plate. Recessed portions having predetermined depths are formed in a region of the surface of the silicon substrate, where the flow paths are formed, and discharge ports are formed above the recessed portions.
