    Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board for mounting thereon a semiconductor chip and to provide a method for flip-chip bonding the semiconductor chip to the printed wiring board. SOLUTION: A printed wiring board 1 for flip-chip bonding thereto a semiconductor chip 7, includes each circuit pattern 6a connected with each conductive protrusion 8 provided in each corner portion of the semiconductor chip 7 and an insulation layer 3a for holding thereon the circuit patterns 6a. Furthermore, at each portion of the insulation layer 3a which is present near each circuit pattern 6a connected with each conductive protrusion 8, each protective pad 9 corresponding to each corner portion of the semiconductor chip 7 is formed.

    Abstract: An opening (15) is formed in an insulating film (14) which covers a electric line (12) formed on a substrate (11) and a pad connecting portion (13) of the electric line is exposed and a pad is constructed. In this case, the pad connecting portion is set to a size having an allowance size 2 larger than a size L of the pad to be formed. The opening is set to a size having an allowance size 2d larger than a width D of the pad connecting portion and is formed so as to cross the pad connecting portion. Even when a positional deviation occurs in an opening which is formed in an insulating film, it is permitted and pads each having a predetermined area are formed with a predetermined positional relation.

    Abstract: PROBLEM TO BE SOLVED: To provide a multilayer circuit board in which a micro-crack or migration hardly occur even if a RFP is arranged near edges.
    SOLUTION: A multilayer circuit board 10 is provided with an inner layer 13 having an RFP 16, outer layers 14 and 15, RFP lands 19 and 20, and conductors 21 and 22. Outside edges 23 and 24 of the conductors 21 and 22 extend outward from outside edges 25 and 26 of the RFP lands 19 and 20. Even when the multilayer circuit board 10 is heated and a stress is developed near a buried through hole 16, since the conductors 21 and 22 are formed so as to cover the RFP lands 19 and 20, a reaction takes place against the stress and the occurrence of micro-cracks is suppressed. Furthermore, since the conductors intercept the permeation of moisture into the vicinity of the buried through hole from the surface, the occurrence of copper migration is suppressed.

    Abstract: PROBLEM TO BE SOLVED: To provide a through-hole structure used for connecting connectors for high frequency to a printed board and to provide a printed board containing the through-hole structure. SOLUTION: The through-hole structure 2 used for connecting connectors to the printed board 1 contains a through-hole 3 for signal which is treated to become conductive for supplying signals, through-holes 4 for power which are treated to become conductive for supplying electric power, and dielectric constant adjusting sections 5 formed between the through-holes 3 and 4. The printed board 1 contains the through-hole structure 2.

    Abstract: PROBLEM TO BE SOLVED: To provide a hole forming method and a hole forming device for forming a hole in which the hole diameters of the upper part and the bottom part are the same in hole forming using a laser. SOLUTION: The hole forming device is composed in such a manner that a laser 10 is vertically irradiated to a substrate 12, and a hole with a taper shape in which the hole diameter in the bottom part is smaller than that in the upper part. Further, in the hole forming device, the tapered hole is irradiated with the laser 10 so as to be tilted to the substrate 12, and the hole diameters in the upper part and the bottom part are made uniform. By applying the laser 10 so as to be tilted in this way, a straight hole 14 can be formed. COPYRIGHT: (C)2004,JPO&NCIPI

    Abstract: PURPOSE: To form pads having a prescribed area with prescribed positional relation by allowing positional deviations generated on apertures formed on an insulating film. CONSTITUTION: Apertures 15 are formed on an insulating film 14 covering wirings formed on a substrate 11 and pad constitution parts 13 are exposed to constitute pads. In this case, each pad constitution part 13 has an excess dimension 21 exceeding the dimension L of each pad and each aperture 15 has an excess dimension 2d exceeding the width of each pad constitution part 3 and is formed so as to cross the pad constitution part 13.
