摘要:
In an ink-jet type recording head including a nozzle plate provided with nozzle openings, a spacer provided with partitions for partitioning pressure generating chambers, ink supply ports and reservoirs, and a plate member sandwiched and fixed together. Displacement of the plate member is produced by piezoelectric vibrators to thereby generate ink droplets. The spacer is formed by anisotropic etching of a silicon single crystal substrate so that the pressure generating chambers, the ink supply ports and the reservoirs are formed as through-holes communicated with each other. Accordingly, etching conditions for the respective through-holes are made equal to each other. Particularly, through-holes small in sectional area such as the pressure generating chambers and the ink supply ports can be formed with a high accuracy.

An ink jet printer head includes a spacer including pressure generating chambers continuous to nozzle openings, ink supply paths, and reservoirs, a cover member for covering the pressure generating chambers in a sealing fashion, and pressure generating means for generating pressure in the pressure generating chambers in accordance with print data. In processing a silicon single-crystal substrate vertically oriented in (110) by anisotropic etching process, one of the walls of a path hole for forming a pressure generating chamber is aligned with one of the walls of a path hole for forming a reservoir. Walls defining the path hole for forming a pressure generating chamber, which are located in the vicinity of a nozzle opening, are connected to each other at an obtuse angle. As a result, the ink supply path serving as a narrow path for ink flow and the pressure generating chamber are formed as smooth flow paths. The walls in an area in the vicinity of the nozzle opening where ink tends to stay are substantially equally distanced from the nozzle opening. A smooth flow of ink is ensured.

The invention provides a method of forming a wiring pattern in which a conductive material layer is formed in a pattern formation region having a first region, which is bordered by a bank pattern and has a first width, and a second region, which touches the first region and has a second width smaller than the first width, on a substrate, by discharging a droplet of a conductive material in a liquid phase using a droplet discharge device. The method includes forming the conductive material layer to cover the first region and the second region, by discharging the droplet having a diameter smaller than the first width and greater than the second width toward the first region. In this case, the droplet is discharged such that the droplet lands at a position that faces a boundary line between the first region and the second region.
