    摘要: Disclosed are a highly reliable circuit board and a method of stably manufacturing the circuit board, wherein an insulator made from a specific organic insulating material is provided under a highly stressed conductor for preventing occurrence of cracks in the insulator. In addition, a method of correcting a wiring of a ceramic board is additionally adopted. The circuit board includes a thick film wiring board 1 having a first conductor pattern 2 and a thin film layer laminated on the first conductor pattern 2. The thin film layer includes a first insulator 5 on the first conductor pattern 2; a second insulator 10 on the first insulator 5; a second conductor pattern 8 formed on the first insulator 5 in such a manner as to partially pass through the first insulator 5 and to be electrically connected to the first conductor pattern 2; a wiring pattern 9 for circuit correction formed on the first insulator 5; and a third conductor pattern 11 passing through the first insulator 5 and the second insulator 10 and electrically connected to the second conductor pattern 8.

    摘要: A multilayer wiring system for preventing the generation of fixing failure due to an organic residue, eliminating an increase in the number of processes and reducing an area necessary for bonding of the cap and its fabrication method. The multilayer wiring board includes at least one wiring layer made of a conductor, at least one insulating layer made of an organic matter and a board. The wiring layer and the insulating layer are alternately laminated on the board and a cap is provided for covering the insulating layer and the wiring layer. The wiring layer has a wiring pattern for forming a wiring and a frame pattern for surrounding the wiring pattern. This frame pattern includes vent holes. The insulating layer has a shield structure made of an inorganic matter around the outer peripheral portion thereof and/or in the interior thereof. The shield structure is formed of the frame patterns continuously connected to each other and the cap is joined to an uppermost layer of the shield structure.
