    摘要: PROBLEM TO BE SOLVED: To provide a semiconductor device capable of preventing semiconductor chip damage even when a solder bonding agent is employed to join a rear surface of a semiconductor chip to a junction face of a chip junction of an island and a die pad.SOLUTION: One surface 5 of a resin substrate 4, an island 6, which is rectangular in a planar view, and outward extensions 8 that outward extend from respective four corners of the island 6 are formed integrally. The surface 7 of the island 6 is a junction face for joining a rear surface 10 of a semiconductor chip 1 with a solder bonding agent 11 and has a smaller area than that of a rear surface 10 of a semiconductor chip 1.

    摘要: PROBLEM TO BE SOLVED: To provide a manufacturing method of a compound element capable of further increasing the effect by surface tension, by forming a high wettability area and a low wettability area by a simple method. SOLUTION: Liquid (an adhesive) 14 is dripped on a projecting part 13 of a base 11. The dripped liquid 14 expands by wetting a surface of the projecting part 13, and is finally stabilized in a semispherical state by the surface tension. Next, a joining object member 12 is contacted with the surface liquid 14 of the projecting part 13, and in a moment, the liquid 14 expands by wetting a surface of the member 12, and stops in an end part. At this time, the member 12 held by weak suction rotates and moves so as to align with a shape of the projecting part 13 of the base 11, and afterwards, the member 12 is further lowered, and is completely contacted with the projecting part 13 of the base 11.
