In this semiconductor device, the through-hole is formed in the substrate, and is located under the conductive pattern. The insulating layer is located at the bottom surface of the through-hole. The conductive pattern is located on one surface side of the substrate. The opening pattern is formed in the insulating layer which is located between the through-hole and the conductive pattern, where the distance r3 from the circumference of the opening pattern to the central axis of the through-hole is smaller than the distance r1 in the through-hole. By providing the opening pattern, the conductive pattern is exposed at the bottom surface of the through-hole. The bump is located on the back surface side of the substrate, and is formed integrally with the through-electrode.

A terminal pad is formed on an active surface of an LSI chip, and a composite barrier metal layer is provided over this terminal pad. In the composite barrier metal layer, a plurality of low-elasticity particles composed of a silicone resin is dispersed throughout a metal base phase composed of NiP. The composite barrier metal layer has a thickness of, e.g., 3 μm, and the low-elasticity particles have a diameter of, e.g., 1 μm. A semiconductor device is mounted on a wiring board by bonding a solder bump to the composite barrier metal layer. The low-elasticity particles are thereby allowed to deform according to the applied stress when the semiconductor device is bonded to the wiring board via the solder bump, whereby the stress can be absorbed.

In a conventional UBM made of, for example, Cu, Ni, or NiP, there has been a problem that when an electronic component is held in high-temperature conditions for an extended period, the barrier characteristic of the UBM is lost and the bonding strength decreases due to formation of a brittle alloy layer at a bonding interface. The present invention improves the problem of decrease in long-term connection reliability of a solder connection portion after storage at high temperatures. An electronic component comprises the electronic component includes an electrode pad formed on a substrate or a semiconductor element and a barrier metal layer formed to cover the electrode pad and the barrier metal layer comprises a CuNi alloy layer on the side opposite the side in contact with the electrode pad, the CuNi alloy layer containing 15 to 60 at % of Cu and 40 to 85 at % of Ni.

A pivotal lever has a first therapeutic member and a second therapeutic member positioned below the first member, for the members to grip and knead the shoulder of the person to be massaged as by the fingers of the acupressurist. A massage unit 20 comprises a pair of left and right pivotal levers 100 pivotally movably arranged on a chassis 21, and a first therapeutic member 200 and a second therapeutic member 300 arranged on each of the pivotal levers 100 and movable toward and away from each other. The first and second therapeutic members 200, 300 have motion conversion means 400 coupled thereto for converting the pivotal movement of the pivotal lever 100 into the movement of the first and second therapeutic members 200, 300 toward and away from each other. The first and second therapeutic members 200, 300 grip the shoulder of the person when moved toward each other and release the shoulder from the gripping action when moved away from each other to thereby cause the members to simulate the gripping and kneading movement of the acupressurist.
