摘要： A method for forming through holes, which has laser beam as the light source to project the laser beam to the work object using an optical system through a photomask for the formation of through holes on the work object by ablation processing, comprises the steps of increasing the concentration of the optical processing energy contributing to the process using the reflected beam created from the work object in the laser ablation processing; and forming each of through holes having the configuration enabling the narrower end to be changed to the wider end in the incident direction of laser beam. With the structure thus arranged, it becomes possible to increase the energy concentration that contributes to the process as compared with the usual ablation processing, because the reflected beam created in the ablation processing can be utilized again for the optical processing. Then, each of the through holes can be formed easily in the configuration in which the narrower end changes to the wider end in the incident direction of laser beam, which cannot be easily processed by the application of the usual ablation processing.
摘要翻译：一种用于形成通孔的方法，其具有激光束作为光源，以使用光学系统通过光掩模将激光束投射到工件上，用于通过消融处理在工件上形成通孔，所述方法包括以下步骤：增加使用在激光烧蚀处理中从工件上产生的反射光的过程的光处理能量的浓度; 并且形成具有使得较窄端部能够在激光束的入射方向上更宽的端部的每个通孔。通过这样布置的结构，由于在烧蚀处理中产生的反射光束可以再次用于光学处理，因此可以增加与通常的烧蚀处理相比有助于工艺的能量集中。然后，可以容易地形成每个通孔，其中较窄的端部变化到激光束的入射方向上的较宽端部的结构，这不能通过施加通常的消融处理而容易地处理。

摘要： A laser working method which can easily and accurately work a fine and complicated shape by irradiation of a laser beam is provided. When a plurality of channel grooves (3) are laser worked on a second board (1) constituting a liquid jet recording head and projections (6) are laser worked on the joint surface of groove walls (4) between the channel grooves and the like, the projections (6) are first worked and formed by irradiating the laser beam through a first mask pattern (10) of a high space frequency arranged by transmitting portions (11) to work the projections (6) and light shielding portions (12). After that, the channel grooves (3) are worked and formed by irradiating the laser beam through a second mask pattern (14) of a low space frequency arranged by transmitting portions (15) to work the channel grooves (3) and light shielding portions (16). The formation of a secondary product due to the laser working can be reduced. Even when the laser working secondary product exists, the influence by the secondary product can be reduced and the working can be performed. A fine and complicated shape can be stably and cheaply worked.

摘要： A method for manufacturing an ink jet recording head, which is provided with a plurality of ink paths structured by bonding a second substrate having a plurality of grooves arranged thereon to form ink paths corresponding to a plurality of discharge openings, together with a first substrate having discharge energy generating devices arranged in the ink paths, respectively, comprises the step of processing the grooves constituting the ink paths on the second substrate by means of formation processing, and laser processing, divisionally. This method makes it possible to process ink flow paths with ease and good production yield even when the ink flow paths are arranged in such a high density that its formation becomes difficult by the application of formation processing, and also, to reduce the total energy of laser when ink flow paths are processed as compared with the method adopted conventionally. The required load given to the optical system of a laser processor is made smaller accordingly.

摘要： A laser processing method comprises at least one of a laser light source, a beam shaping optical system for shaping laser beams, a mask having specific patterns corresponding to the processing configuration of a work, an illumination optical system for illuminating the mask, and a projection optical system for focusing the pattern images of the mask on the processing surface of the work by a specific magnification. This mask is provided with an extinct portion smaller than the quotient of the resolution and specific magnification of the projection optical system. With the method thus arranged, a work can be processed to provide complicated three-dimensional grooves having irregularities in the direction of laser irradiation by one-time processing. Also, the extinct portions make it possible to easily and finely adjust the extinction so that the precision of work processing is enhanced.

摘要： A common recess, grooves, and common recess and/or column members (7) in the grooves are formed on a base board at the same time, and such board is made a second base board (5), which is coupled to a first base board (2) on which elements (1) for liquid discharging energy are formed; hence obtaining an ink jet recording head provided with a filter unit in an arbitrary position in the region formed by the ink paths and the common liquid chamber (4). The filter unit (8) can be processed by a single processing in the ink paths and/or the common liquid chamber (4) to make it possible to prevent disabled discharge from taking place due to dust particles intermingled at the time of head manufacture. In this way, the discharging stability is enhanced, making a high-speed printing possible. A work is efficiently processed by a single processing which is performed to process a three-dimensional configuration with respect to the direction in which the laser beam is irradiated.
