Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a multilayer substrate reduced in adhesion defect. SOLUTION: In a chamber 10, an adhesive material 5 is attached to a first ferrite substrate 2 and pressure is reduced. Since the pressure is reduced before adhering a second ferrite substrate 4, an air bubble is deaerated from the sufficiently exposed adhesive material 5. After the pressure is reduced, the pressure in the chamber 10 is boosted to air pressure lower than the atmospheric pressure. Thus, the volume of the air bubble remaining in the adhesive material 5 is reduced according to a Boyle Charle's law. The air bubble whose volume is reduced float on the surface of the adhesive material 5 and is diffused. After boosting, the first ferrite substrate 2 and the second ferrite substrate 4 are adhered through the adhesive material 5 and the chamber 10 is boosted to the atmospheric pressure. Thus, the volume of the air bubble mixed in the adhesive material 5 during adhesion is reduced according to the Boyle Charle's law. The air bubble whose volume is reduced is diffused from the surface of the adhesive material 5. COPYRIGHT: (C)2007,JPO&INPIT

Abstract translation: 要解决的问题：提供减少粘附缺陷的多层基板的制造方法。 解决方案：在腔室10中，将粘合剂材料5附接到第一铁氧体衬底2上，并且减小压力。 由于在粘附第二铁氧体基板4之前压力降低，因此气泡从足够暴露的粘合材料5脱气。在压力降低之后，将室10中的压力提升到低于大气压力的空气压力。 因此，根据Boyle Charle定律，残留在粘合材料5中的气泡的体积减小。 体积减小的气泡浮在粘合剂材料5的表面上并被扩散。 升压后，第一铁素体基板2和第二铁氧体基板4通过粘合材料5粘合，将室10升压至大气压。 因此，根据Boyle Charle定律，在粘合期间混合在粘合剂材料5中的气泡的体积减小。 体积减小的气泡从粘合剂材料5的表面扩散。版权所有（C）2007，JPO＆INPIT

The coating are not left at all at the part of the exposed peripheral face 11A, and the peripheral face is formed into a curved face, having no convex-concave. The laser output of the laser irradiation is 4.5 W, and a Q-switch frequency is 40 kHz to 80 kHz. The scanning speed is 100 mm/s, when the diameter of the conductor 11 is 0.2 mm. A distance between an fθ-lens and the surface of the insulated coated conductor 1 is set to f-2 mm, scanning is conducted in a defocused state, and irradiation is conducted.
