PROBLEM TO BE SOLVED: To reduce warp of a substrate which is caused by curing contraction or the like of an insulating pattern, while the insulating pattern is formed on the substrate so as to be interposed between a semiconductor chip and a conductor pattern. SOLUTION: This substrate is provided with a flexible substrate 11 (insulating film 16) having a chip mounting region for mounting the semiconductor chip on a surface via adhesive agent, a conductor pattern 20 which is formed on the surface of the substrate 11 and electrically connected with the semiconductor chip in a region outside the chip mounting region, and the insulating pattern 21 formed on the surface of the substrate 11 so as to be interposed between the semiconductor chip and the conductor pattern 20. The insulating pattern 21 is partially formed in the chip mounting region. COPYRIGHT: (C)2003,JPO

PROBLEM TO BE SOLVED: To provide a joining method and a joining element that are advantageous for joining a large area and can suppress an increase in manufacturing costs. SOLUTION: In the joining method, metal paste in which a metal nanoparticle is dispersed in an organic solvent is interposed between a first junction section made of metal in a first member and a second junction section made of metal in a second member, the metal nanoparticle is sintered by heating at least the metal paste, and the first junction section is joined to the second one as a joining member having a void inside. In the joining method, at least one of the configuration condition of the metal paste and the sintering condition of the metal nanoparticle is adjusted, thus laminating and forming a plurality of types of junction layers having mutually different porosity, namely the occupation ratio of the void, as the joining member between the first and second junction sections so that the porosity differs between adjacent junction layers.

PROBLEM TO BE SOLVED: To provide a packaging method for electronic components that allows an adhesive to be evenly disposed on a surface of a supporting substrate, such as a wiring substrate, on which electronic components are firmly fixed in response to pneumatic discharged from a semiconductor bonding tool for firmly fixing electronic components on the substrate using the adhesive. SOLUTION: As a method for packaging electronic components onto a supporting substrate 10, the present invention provides an adhesive disposition step for disposing an adhesive 12 to multiple places S1 to S5 on the supporting substrate 10 where electronic components are mounted and an electronic component mounting step for firmly fixing the electronic components by use of a suction tool to the mounting places S1 to 5 in a predetermined order through the adhesive 12. In the above adhesive disposition step, the volume centroid of adhesives 12-2 to 12-5 disposed at mount places S2 to S5 where an electronic component is mounted in the N-th order is made to be inclined in response to a deformed part owing to pneumatic blown off from the suction tool when an electronic component is mounted at the mount place S1 where an electronic component is mounted before the N-1th order.
