Abstract: PROBLEM TO BE SOLVED: To provide a thermal ink jet head in which films can be formed at a high speed and a short circuit between discrete electrodes is prevented even when defects such as pinholes occurs in an insulating layer. SOLUTION: A radiation layer 26 is formed on a narrow face of about a half of a glass substrate 25, then the insulating layer 28 is spread on the whole face of the substrate. A heating resistor 29a is disposed above a right end of the radiation layer 26. A common electrode 31b formed to the whole face above the radiation layer 26 is connected to a left end of the heating resistor 29a. The discrete electrode 31a formed onto the insulating layer 28 of a part where the radiation layer 26 is not formed is connected to a right end of the heating resistor 29a. An ink supply groove 33, an ink supply hole 34 and a diaphragm 32 are formed, an orifice plate 35 is layered, and an orifice 36 is bored. The glass substrate 25 cut as a chip is die bonded by a die bonding agent 39 to a radiation plate 37. Then, the radiation layer 26 exposed to the left end and the radiation plate 37 are thermally coupled by a heat transfer paste 41. Since the radiation layer 26 is absent immediately below the discrete electrode 31a, no short circuit takes place even if the insulating layer has the pinhole.

Abstract: PROBLEM TO BE SOLVED: To provide an anisotropic etching method in which occurrence of an ejection nozzle having an incomplete shape or incomplete electrical connection at the electrode terminal part due to readhesion of the etching residue of metal mask is prevented. SOLUTION: An orifice plate 58 is formed on the uppermost layer of a heating part 52, a common electrode 53, a discrete interconnection electrode 54, an ink supply trench 55, an ink supply hole 56, a barrier wall 57, and the like, formed on a chip substrate 51 and a metal mask film 63 is formed thereon by sputtering thus forming a pattern 63-1. Furthermore, a nonmetallic thick resist film 64 having an etching select ratio of 1:1 with respect to the orifice plate 58 is formed thereon with the same thickness as the orifice plate 58 thus forming a pattern 64-1. Subsequently, helicon wave dry etching is performed according to the patterns 63-1 and 64-1 to make an ejection nozzle 62. The thick resist film 64 is etched substantially over the entire etching period and removed gradually and the metal mask film 63 is etched by only a small thickness d in the final stage.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printing head which is prevented from a substrate break and is advantageous in improving a manufacturing yield. SOLUTION: An ink groove projection 28-1 is formed to a central part of an ink groove 28. An ink supply hole 29 is formed to a position whereat a communication port 30 to the ink supply hole 29 is formed in the ink groove projection 28-1. The communication port 30 is hence disposed so that a central position of the communication port 30, namely, a position of a center axis of the ink supply hole 29 is shifted by a predetermined distance to a center line in a breadth direction of the ink groove 28. A structure of the ink groove 28 in the vicinity of the ink supply hole 29 is improved in strength than a structure of the conventional ink groove where the center line in the breadth direction agrees with the axial center position of the ink supply hole. Accordingly, concentration of a mechanical stress when sand blasting is carried out or when a top plate is attached is eased, and the substrate break in a longitudinal direction of the ink groove 28 is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing ink jet printer heads whereby residues generated by etching a mask to work discharge nozzles are prevented from adhering to discharge nozzles and electrode terminals. SOLUTION: An orifice plate 15 with thermoplastic polyimide adhesive layers applied to both faces is first attached onto a diaphragm not illustrated on which the mask film 16 is formed. The resist mask 17 is formed to a limited neighborhood of a region where discharge nozzles are to be formed. The mask film 16 is then etched. Subsequently the resist mask 17 is removed to expose the mask film 16. A thick film resist 19 is coated and patterned to open only the discharge nozzle part and the electrode terminal part. Discharge nozzles 21 are bored to the orifice plate 15 by helicon wave etching. Overetching is carried out for several minutes at this time to a level so that the orifice plate 15 is etched only by a thickness d. The thick film resist 19 is completely removed.

Abstract: PURPOSE:To seal a liquid crystal injection port always with a specified amt. of a sealing material. CONSTITUTION:The sealing material 16 prepd. by incorporating fillers 18 having the diameter larger somewhat than the diameter of the spacers 13 into a thermoplastic resin 17 is arranged by a screen printing method or dispensing method, etc., on the rear surface of an upper film substrate 15 in the part corresponding to the central part of the liquid crystal injection port 14 formed at a sealing material 12 disposed on a lower film substrate 11. In such a case, the amt. of the sealing material 16 to be arranged is kept always constant. The sealing material 16 is held intact and both film substrates 11, 15 are stuck to each other via the sealing material 12 when both film substrates 11, 15 are superposed on each other and are heated under a low pressure applied thereon. Next, injection of liquid crystals 6 is executed. The fillers 18 are crushed or are bitten into both film substrates 11, 15 and the thermoplastic resin 17 is softened and fluidized to hermetically close the liquid crystal injection port 14 when a high pressure is applied at the part of the sealing material 16 and the sealing material is heated.
